252 COlLECIIOlfS FROM MELANESIA. 



102. PMyxia crassipes, Bdl. 



Of this species, wHolt is said by Mr. Haswell to be extremely 

 common at Port Jackson, a very small male was dredged at that 

 locality in 5-7 fms. (No. 104), and another, larger, male in 0-5 fms. 

 (second collection). 



Besides the specimens from Port Jackson {Cuming and J. Maogil- 

 livray) mentioned by Bell, the Museum possesses one from Flinders 

 Island, Bass Straits (F. M. Bayner, H.M.S. ' Herald '), and others, 

 without special locality, from Dr. Bowerbank and W. A. Miles, 

 Esq. 



It is of interest to note that there are two other species of this 

 genus recorded from Port Jackson, and agreeing with PMyxia cras- 

 sipes in possessing a 4-lobed front, which yet appear to be distinct ; 

 they are Phlyxia quadridentata*, a species recorded from Port 

 Jackson by Stimpson, and Phlyxia ramsayi, Haswell {t. c. p. 127). 



103. Phlyxia lambriformis. 



Phlyxia lambriformis, Bell, Trans. lAnn. Soc. xxi. p. 304, pi. xxxiv. 



fig. 2 (1856); Cat. Leucos. Brit. Mus. p. 17 (1855); Haswell, 



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 collection 

 from Prince of Wales Channel, 9 fms. (No. 157), and four males and 

 a female from Port Darwin, 7-12 fms. (mostly No. 173). 



There are, besides, two specimens in the British Museum from 

 the ' Eattlesnake ' collection, obtained at Bass Straits, and one 

 from the same collection, without special locality. 



It is recorded by Mr. Haswell from Princess Charlotte Bay and 

 Holborn Island near Port Denison, and also from Port MoUe, Wliit- 

 sunday Passage (as P. petleyi). 



After a careful comparison of Mr. HasweU's description and 

 figure of P.pethyi in the Catalogue of Australian Stalk- and Sessile- 

 eyed Crustacea with Prof. Bell's types of P. lambriformis in the 

 Museum collection, I am unable to regard the two as distinct 

 species. Prof. Bell's figure is from an adult male in which the 

 rostrum, tubercles of the carapace, and teeth of the antero-lateral 

 margins are aU very prominent, whereas Mr. HasweU's description 

 was based upon a female and smaller male. Moreover, Bell's short 

 description is misleading in one or two particulars — e. g. he describes 

 the carapace as carinated, whereas the keel in question extends only 

 over the depressed postfrontal portion of the carapace, from the 

 back of the rostrum to the gastric region. 



104. Nursia sinuata, Miers. 



Of this species three specimens, a male and two females, are in 

 the coUeotion (No. 123), but, unfortunately, the exact locality is not
