788 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. [NoV. 5, 



strata abound in Crustacea, such as Glyphcea and Hoploparia, which 

 are evidently closely allied to the Crayfishes. 



The great difficulty is, not to account for the Crayfishes where we 

 find them, but to understand their absence over so large a part of the 

 Old World and of intertropical America. Whether this is to be 

 explained by extensive alterations in geographical conditions since the 

 extinction of the Protastacus stock, or by the competition of Prawns 

 and freshwater Crabs, or by some other circumstance at present 

 unknown, is a very interesting subject for further inquiry. 



Postscript, Oct. 24, 18/8. 



Since this paper was read, my friend Mr. Moseley, F.R.S., has 

 written for and obtained specimens of the " Crayfish " said to exist 

 in the fresh waters of the Cape-Yerd Islands. They belong to the 

 genera Atya and Paleemon. Moreover, by the intervention of Sir 

 Joseph Hooker, I have procured a considerable number of fresh- 

 water Crustacea from Jamaica. But these also all belong to Atya 

 and Palfcmon. I suspect that all Sloane's "Crayfishes" are 

 simply Prawns. The largest example of one of the species sent to 

 me measures sixteen inches in length when the great chelate limbs 

 are fully extended.— T. H. H.

 Arthur Grote, Esq., V.P., in the Chair. 



The Secretary read the followiug reports on the additions to the 

 Society's Menagerie during the months of* June, July, August, 

 September, and October 1878 : — 



The total number of registered additions to the Society's Mena- 

 gerie during the month of June was 159, of which 35 were by birth, 

 75 by presentation, 29 by purchase, 14 were received on deposit, 

 and 6 by exchange. The total number of departures during the 

 same period, by death and removals, was 73. 



The most noticeable additions during the month of June was as 

 follows : — / 



A Japanese Wolf {Canis hodophylax, of the 'Fauna Japonica,' 

 Mamm. t. 9, p. 38), presented by H. Heywood Jones, Esq., F.Z.S., 

 June 26th, being the first example of this little-known animal we 

 have ever received alive. 



Judging from the present specimen the Japanese Wolf, although 

 nearly allied to Canis lupus, would seem to be a distinct species, to 

 be recognized by its smaller size and shorter legs. 



The Japanese Dog sent to us by Mr. Pryer (see P. Z. S. 1878, 

 p. 115) is quite a different animal, and is, I have no doubt, only a 

 varietv of the domestic do"; or a hybrid.
