182 LIST OF THE AUSTRALIAN PALuEICHTHTES, 



Crossorhinus, Miiller and Henle (1837). 



33. C. BARBATUS, Gmel, sp. The "Carpet Shark" or "Wobbe- 



gong." Southern and eastern coasts of Australia, common. 

 Tasmania, common (Johnston). Port Moresby, New- 

 Guinea (Macleay). 



Note — Mr. S. Scudder (Zool. Norn., Univ. Index, p. 67) 

 gives the orthography of the generic title as Chrossoi'hinuSy 

 but in this he is undoubtedly incorrect, as the first part of 

 the word is derived from the Greek Kpoaaos a tassel — 

 generally used in the plural in the sense of a fringe. 



34. C. TENTACULATUS, Ft7's. Cape York, Q. {Brit. Mus.) Port 



Adelaide, S.A. [Zietz) ; examples from the latter locality 

 are contained in the collections of the Australian Museum, 

 Sydney, and of the South Australian Museum, Adelaide. 

 Though very closely allied, the differences, should they 

 prove constant, are sufficient to justify the separation of 

 this from the preceding species. Taking the various 

 characters mentioned in the description given by Dr. 

 Giinther seriatim, I find that the number of tentacles is 

 inconstant, and this character therefore loses much of its 

 value ; thus in our specimen there are on each side 

 a single minute tentacle on the side of the throat directly 

 under the upper angle of the spiracle, two rather larger 

 a little above and behind the angle of the mouth; a 

 small one on the middle of the hinder section of the 

 upper lip; a short broad strongly compressed lobe at the 

 upper angle of the maxilla, and a similar lobe in the lower 

 angle of the inter-maxillary cleft, and finally a narrow 

 tentacle, equal in length to the spiracle, rises from the 

 inner angle of the lingual flap; all these appendages are 

 simple, whereas in C. barbatus the majority are as a rule 

 bifid, and some occasionally trifid, while they are always
