THE ECHIDNA PROM QrEEffSLAND.

New-Guinea form. In this latter, according to him, rearwards 

 there are five transverse lines of adnate conical papillae lessening 

 in the number of tubercles forwards, and in advance a dozen 

 median linear, double, single, or rosette-like clumps. He remarks 

 also that the palate of tlie Australian Echidna has seven serial 

 transverse spiny lines bearing some resemblance to those of 

 E. himjnii. In the palate of the Queensland animal (woodcut) 

 I find eight approximated, transverse, tuberculated rows poste- 

 riorly, and 3 inch in front of these another more arcuate, — 

 that is, in all nine well-marked tuberculate cross ridges. Fur- 

 thermore, there are eight somewhat scale-like cross arches, in one 

 or two of which tracings of serrate free border is visible with a 

 hand-lens. These latter are situate nearly equidistant, and about 

 0*2 inch apart, the hind one being opposite the anterior border 

 of the orbito-zygomatic arch. The anterior palatine siit opens 

 between the third and fourth front ones. Thus, of the New- 

 Guinea and Queensland examples, both possess seventeen palatal 

 ridges ; but the pattern of these is un- 

 like, that of the Queensland animal, to 

 all intents and purposes, resembling 

 that extant in the common E. liystrix. 



With respect to the cranium, I com- 

 pared that from Queensland side by side 

 with those in the CoUege-of-Surgeous 

 Museum, viz. five in all, intact. Of these 

 specimens of Echidna-'&\.\i\\^, that num- 

 bered 1705 A is labelled E. Jiystrioc, from 

 Grafton, Clarence Eiver, New S. AVales; 

 No. 1708 A is that of a young male 

 which lived in the Zoological Gardens ; 

 No. 1708 B is that of a complete skeleton 

 of a young E. setosa from Tasman's Pe- 

 ninsula. Of No. 1705, E. hystrix, the 

 locality is unrecorded; and No. 1704a 

 is marked in the Catalogue, " Skull of an 

 Echidna^ Moreover Prof. Flower lately 

 has had added to the collection a cast 

 of the skull of Echidna (AcanthoyJossus) 

 hruijnii (No. 1723 a), presented by Prof. 

 Gervais.
