304 COLLECTIONS FROM MELANESIA.of Wales Channel (7-9 fms.). The antennae are imperfect. Twospecimens, of unknown locality, are in the British Museum from thecollection of H.M.S. Herald.''The mandible, in its broad and strongly dentated apex, closely resemblesthat of C. schi'ddtei.Cirolana latisti/lis, Dana, from the Balabac Straits, is very imperfectlydescribed, but appears to be distinguished from this species bythe much broader inner ramus of the uropoda.(i Cirolana lata, HasweU, var. Integra.Three small specimens from Albany Island, 3-4 fms., are referredwith much hesitation to this species. In the broadly ovoid form ofthe body, with its longer first thoracic segment and short postabdomen,they resemble Mr. Haswell's figure and description* ; butthe terminal postabdominal segment is less acute than in the figure,and there is no tooth upon the inner edge of the inner ramus of theuropoda. I may add, in reference to some points that are notmentioned in Mr. Haswell's description, that the eyes are black andsubijuadrate, the median rostral point prominent and prolongedbetween the bases of the anteunules to or nearly to the apex ofthe interantennal plate, which is nearly of the same form as inC. scJiiodtei, but is without a superficial tooth ;the apex of themandible is broad and dentated as in other species of the genus ; thebasal joint of the antennules is large and considerably dilated ; thefiagellum of the antennae (which is short and scarcely reaches beyondthe posterior margin of the first body-segment, as in Haswell's figure)is 13-15-jointed.7. Rocinela orientalis, Schiddte 4' Meinert.A single female is referred here in Dr. Coppinger's collection fromPrince of AVales Channel, 7-9 fms., which has lost the inner ramusof both uropoda.Specimens are in the British-Museum collection from MoretonBay.If a male and female from Ceylon {E. W. H. Holdsworth) anda male from the Gulf of Suez are correctly regarded as identicalwith this species (and they do not seem to differ markedly from theAustralian examples), this must be a widely distributed Orientalform. A large specimen from the West-African coast (withoutspecial indication of localitj') comes very near to this species, buthas a more acute and prolonged front and posterior epimera, anddiffers slightly in the proportionate length of the joints of theantennae and antennules, and may be distinct. Messrs. Schiodteand Meinert's types were from the Philippines and Calcutta.Mr. Haswell has described a species, Rocinela vigilavs, fromHolborn Island, near Port Denison {vide Cat. p. 285), which seems* Troc.
