—;252 COLLECTIONS FROM MELANESIA.102. PMyxia crassipes, Bell.Of this species, which is said by Mr. Haswell to bo extremelycommon at Port Jacksou, a very small male was dredged at thatlocality in 5-7 fms. (No. 104), and another, larger, male in 0-5 fms.(second collection).Besides the specimens from Port Jackson {Cuming and /. Macgillivray)mentioned by Bell, the Museum possesses one from FlindersIsland, Bass Straits {F. M. Rapier, H.M.S. Herald ' '), and others,without special locality, from Dr. Bowerbank and W. A. Mile.s,Esq.It is of interest to note that there are two other species of thisgenus recorded from Port Jackson, and agreeing with Plilyxia crassipesin possessing a 4-lobed front, which yet appear to be distinctthey are Phhjxia quadridentata* , a species recorded from PortJackson by Stimpson, and Phhjxia ramsai/i, Haswell (t. c. p. 127).103. Phlyxia lambriformis.Phlyxia lambriformis, Bell, Trans. Linn. Soc.xxi. p. 304, pi. xxxiv.\ fig. 2 (1855); Cat. Leucos. Brit. Mus. p. 17 (1855); Hasivell,Cat. Austr. Crust, p. 124 (1882).Phlyxia petleyi, Haswell, t. c. p. 125, pi. iii. fig. 3 (1882).A female was received with Dr. Coppinger's second collectionfrom Prince of Wales Channel, 9 fms. (No. 157), and four males anda female from Port Darwin, 7-12 fms. (mostly No. 173).There are, besides, two specimens in the British Museum fromthe ' Eattlesnake ' collection, obtained at Bass Straits, and onefrom the same collection without special locality.It is recorded by Mr. Haswell from Princess Charlotte Bay andHolborn Island near Port Denison, and also from Port Molle, WhitsundayPassage (as P.petleyi).After a careful comparison of Mr. Haswell's description andfigure of P. petleyi in the Catalogue of Australian Stalk- and SessileeyedCrustacea with Prof. Bell's types of P. lambriformis in theMuseum collection, I am unable to regard the two as distinctspecies. Prof. Bell's figure is from an adult male in which therostrum, tubercles of the carapace, and teeth of the antero-lateralmargins are all very prominent, whereas Mr. Haswell's descriptionwas based upon a female and smaller male. Moreover, Bell's shortdescription is misleading in one or two particulars e.g. he describesthe carapace as carinated, whereas the keel in question extends onlyover the depressed postfrontal portion of the carapace, from theback of the rostrum to the gastric region,104. Niirsia sinuata, Miers.Of this species three specimens, a male and two females, are inthe collection (No. 123), but, unfortunately, the exact locality is not* Ebalia quadridentata. Gray, Zool.
