34 with long inwardly directed spine, on outer distal corner, second segment with somewhat shorter similar spine, last segment with similar spine about half length of that of the first segment, exopod segments otherwise armed with plumose setae as in the figure; endopod first segment with a row of short spinules along outer edge and a patch of longer spinules at outer distal comer, second segment with a dense patch of long spinules along outer edge, third segment with a few long spinules at outer proximal edge, endopod with plumose setae as in the figure. Leg 3 (Figure 69a) exopod first segment with stout, slightly recurved spine, on outer distal corner, second segment with short, weak, spine on outer distal corner, last segment with 3 weak spines and 4 plumose setae; endopod with 2 segments bearing plumose setae as in the figure. Leg 4 (Figure 696) exopod first segment outer edge produced as approximate right angle at distal two-thirds; last segment with distalmost spine 2/2 times length of others (442 X 177 /*m). Leg 5 represented by 3 short plumose setae near edge of genital segment at distal three-fourths. MALE.—Body form as in Figure 69
NUMBER 3 1 1 35 corner and an inner seta, last segment with 3 outer spines and 5 terminal to inner setae; endopod first segment with an inner seta, second segment with a patch of long spinules along outer edge and 2 inner setae, last segment with a patch of long spinules on outer edge and 6 setae. Third leg (Figure 72a) basipod with scattered short spinules near outer margin; exopod first segment with a prominent spine on outer distal corner, second segment with a short spine on outer distal corner and inner seta, last segment with 3 short outer spines and 4 terminal to inner setae; endopod first segment with an inner seta, last segment with 6 terminal setae. Fourth leg (Figure 72b) basipod with a small seta on outer distal corner; exopod first segment with a fringed seta (112 /Am) on outer distal corner, second segment with fringed seta (136 /*m) on outer distal corner, last segment with 3 fringed setae (153, 165, and 206 /*m long respectively), a fringe at base of each seta. Fifth leg represented by 4 setae near the posterior distal corner of the genital segment. MALE.—Body form as in Figure 72c. Total length 2.39 mm, greatest width 1.30 mm. Genital segment about as long as wide (0.43 X 0.45 mm). Abdomen 2-segmented segments measure 88 X 250 fixn and 292 X 280 jan (length X width) respectively. Caudal rami as in female. Appendages as in female except as follows. Second antenna (Figure 72d) with accessory process on claw and bossed areas on segments as illustrated. Postoral process (Figure 72«) with accessory process at distal two-thirds. Maxilliped (Figure 72/) base with 2 well-developed processes opposing tip of claw, portion of claw distal to seta proportionately shorter than in female. Fifth leg represented by 4 setae at mid-lateral margin of genital segment. Sixth leg represented by 3 setae at posterior distal corners of genital segment. REMARKS.—This species has been reported by numerous authors from the west coasts of Europe and Africa (see Margolis, et al, 1975). It is apparently commonly found on species of Trigla but has been reported from several other hosts as well. Our report here is the first from a scombrid host and in light of the many previous literature citations it should not be considered a primary parasite of scombrids. We have included its description here as no complete description exists in modern literature. The specimens studied in this description were compared with material collected by us from Trigla lineata from off Naples, Italy. • Caligus savala Gnanamuthu, 1948 FIGURE 73a-/ Caligus savala Gnanamuthu, 1948:591. Caligus affinis Kurian, 1961:71. Caligus acutus Kirtisinghe, 1964:66. Gnanamuthu described this species from specimens collected from the plankton and a single male from the body surface of Trichiurus savala Cuvier. Kurian collected 2 9 from the body surface of Euthynntu affinis (described as C. affinis). Kirtisinghe, 1964, noted that Caligus affinis was preoccupied and renamed the species Caligus acutus Kirtisinghe. Pillai, 1971:164 redescribed the species from type material of C. savala deposited in the British Museum and placed C. affinis and C. acutus in synonymy with C. savala. The single record of this species from a scombrid indicates that its occurrence on such a host was probably accidental. The female may be characterized as follows. Body form as in Figure 73a. Second antenna (Figure 736) with pointed posterior process on base. Postantennal process (Figure 73c) not strongly curved. Sternal furca (Figure 73a") with tines only slightly divergent and spreading only slightly wider than base. Leg 2 endopod with patches of slender spinules along outer margin of each (entire margin of segment 1 with spinules—usually only at outer corner of other species). Stout spine at the outer distal corner of leg 3 exopod first segment not curved inwardly. Leg 4 exopod (Figure 73/) 2-segmented, distalmost spine about one-third longer than adjacent spine. We did not collect this species and have based the brief description and figures on Pillai's redescription in 1971. Caligus macarovi Gussev, 1951 FIGURES 73g-i, 74o-6 Caligus macarovi Gussev, 1951:408. Caligus fulvipurpureus Shiino, 1954:150. Gussev described this species from specimens collected from 4 species of fish including Auxis and Cololabis saira (Brevoort) from the Sea of Japan.
