Callorhynchus tasmanius (Nob.), Tasmanian Elephant Fish. 



Callorhynchus tasmanius, Richardson, Zool. Proceed., March 10, 1841. 

 C. pinnis pectoralibus ventrales haud attingentibus ; pinnd dorsi secundd pone ventrales 



incipienti, ante lohum anterior em pinna Cauda desinenti ; macula oblongd lacted in 



latere supra pinnam pectoralem. 



This fish differs from C. antarcticus in the tips of the pectoral fins falling considerably 

 short of the base of the ventrals, and in the second dorsal terminating anterior to the 

 commencement of the under caudal fin'. There may be also other differences, but as I 

 have no specimen of antarcticus for comparison, and merely the small figures of Shaw 

 and M. Guerin to refer to, I am unable to point them out. The C. smythii of Bennet, 

 founded on a drawing made by the ofiicer whose name it bears, resembles our specimen 

 in the relative shortness of the pectorals ; but the second dorsal is so unlike that of 



' Cuv. Reg. An. saya of C. antarcticus, " La deuxicme dorsale commence sur les ventrales, et finit vis-H-vis le 

 commencement de celle gut garnit le dessous de la queue."
