Huenia proteus, vara, elongata and heraldica, Adams fy Wliitc, t. c. 

 p. 21 (1848). 



Among the Crustacea collected by Dr. Coppinger are an adult male 

 from Fitzroy Island, Queensland, 10 fms. (Xo. 113); a male and 

 female from Port Denison, 4 fms. (Xo. 122) ; and a male from 

 Thursday Island, Torres Straits, 4-6 fms. 



From the second collection were retained for the British Museum 

 a considerable series from Thursday Island, 3-4 fms. (Xo. 177), a 

 female from Prince of Wales Channel (Xo. 142), and four specimens 

 from West Island, Torres Straits, 7 fms. 



If the various species of Huenia mentioned above are rightly 

 united under the designation H, proteus, it will follow that there 

 are but three species, so far as at present known, referable to this 

 genus — one, H. proteus, ranging (as Mr. Haswcllhas already shown) 

 from Japan and China, southward through the Philippine Islands to 

 the coast of Queensland and islands adjacent; another, H. paeifica, 

 Miers*, from the Fiji Islands ; and a third, H. grandidieri, A. M.- 

 Edwardst, from Zanzibar. It is possible that a larger series would 

 show that H. padfica is no more than a marked variety of the very 

 variable H. proteus ; it differs, however, from all the specimens of 

 that species I have seen in the form of the rostrum, which is not 

 only much longer and slenderer, but also much narrower above at 

 base. 



The other described species of Huenia belong, as I have shown 

 (t. c. pp. 5-6), to other genera. 



7. Egeria arachnoides (Mumph.). 



Here is referred an adult male from Port Molle, 14 fms. (93), a 

 locality already mentioned by Mr. Haswell (Cat. p. 12). 



This specimen presents the characters cited by Mr. Haswell (Proc. 

 Linn. Soc. X. S. Wales, iv. p. 439) as belonging to the specimens he 

 refers to Egeria herbstii — e. g. the orbits are Avidely open above, 

 the eye-peduncles are very short and thick, and there is a spine at 

 the distal end of the third joint of the ambulatory legs, which, 

 however, is very small in the two posterior pairs. These characters 

 can, however, hardly be considered of specific importance ; in a 

 smaller female from Albany Island, 3-4 fms., and in several
