192 COLtECTIONS FROM MEIANESTA. 



specimens in the British-Museum collection scarcely any traces 

 exist of the moral spines above mentioned. I may add that I 

 have obseiTed a considerable degree of variation in the length of 

 the rostrum in the large series of specimens of this species in the 

 collection of the British Museum. In the type specimen of Egeria 

 indica of Leach in this collection the third joint of the outer maxil- 

 Upede does not in reality present any peculiarity of form, nor does 

 this specimen differ from ordinary adult examples of the genus. 



I believe, then, it wiU be necessary to unite under one specific 

 designation the three forms Algeria arachnoides, E. Jierhstii, and 

 E. indica, mentioned by Milne-Edwards*, and that to this species 

 the name arachnoides must be applied rather than the Linnean 

 designation longipes, because Linnseus's description of his Cancer 

 longipes t differs in- several particulars from Egeria arachnoides ; 

 thus he says " manus ovatce, muricatm," or " scahrce," whereas in 

 Egeria arachnoides the hands are always elongated and smooth ; 

 moreover, in the middle line of the carapace are five (not four) 

 tubercles or short spines ; other distinctions might be mentioned. 



Specimens of Egeria arachnoides are in the Museum collection 

 from the Indian Ocean (Hardwiclce), Philippine Islands, Zebu 

 {Ouming), Shanghai {purchased of Jamrach), Port Curtis, Australia 

 {j. Macgillivray), &c. ; several other N.E. Australian localities are 

 recorded by Mr. Haswell. 



The species designated Egeria longipes, M.-Edw., by Adams and 

 WhiteJ, if correctly characterized, differs from any specimen of the 

 genus I have seen in its very much broader, transverse front, and 

 may belong to a distinct species. 



8. Chorilibinia gracilipes.

In Dr. Coppinger's first collection two adult females were received 

 from Port Molle, 14 fms. (No. 93), and one from Albany Island, 

 3-4 fms. (No. 109). In the second collection are a male and female 

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



The types in the Britisb Museum are from Papua, and Mr. Has- 

 well records the occurrence of this species at Cape Grenville. 



9. Paramithrax (CMorinoides) coppingeri, Haswell. 



An adult female is in the collection from Port Darwin, 12 fms., 

 and two small males from Dundas Strait, 17 fms. (No. 161). Has- 

 well's specimens were from Whitsunday Passage (H.M.S. ' Alert ').
