This species was captured by the Expedition on the coast of Chili. 

 Its locality, therefore, is widely different from that of the species of 

 which we have cited the name provisionally and inquiringly as a 

 synonyme, and which, as its name implies, is from the coast of New 

 Zealand. We are, however, inclined to suspect that they are identical, 

 on grounds which will be apparent on comparison of our plate with 

 that in the Zoological Atlas of the Voyage of the Astrolabe, Mammi- 

 feres, PI. XXVIIT, fig. 1, 2, or in Schreber's Saugthiere, PI. CCCLVII. 

 The small circular openings on the throat of D. novcG zeelandioe, repre- 

 sented in the plate of the Voy. Astrolabe, just cited, and particularly 

 in fig. 2, and called " pores," by Messrs. Quoy and Gaimard,''' we re- 

 gard as very probably the work of a parasitic animal infesting it. The 

 fact that these orifices are placed with entire irregularity is, in our 

 opinion, fatal to the supposition that they are a character of the 

 animal. Their absence in the present species is probably a considera- 

 tion of no moment in the question of identity. The dentition of the 

 two species is stated by their describers as exactly the same. 



The following are Mr. Peale's description and remarks on this 

 animal : 



" Snout, head, back, tail, and dorsal fin, blue-black ; belly and pec- 

 toral fin, white ; sides, pale tawny ; eye, small, brown, and surrounded 

 with a black ring which joins the black of the snout ; body, between 

 the dorsal fin and tail, very much compressed. 



" Total length, six feet six inches ; snout, five and three-quarter 

 inches; dorsal fin, measured along the front edge, nine and a* ]ialf 

 inches; along the posterior edge, nine inches; tail, six inches long, 

 sixteen and a half wide ; pectoral fin, eleven and a half inches long,, 

 four inches wide ; from the end of the snout to the eye, twelve inches; 



* " On remarque, sous la macboire infereieure, des^wres formant do petits anneaux; 

 et sur le corps, de petites plaques de stries blanches assez rcgulierenient coutournees."
