blackish. Beak of skull more than half as long again as the brain- 

 cavity. Teeth ^.

 t. 21. f. 1, t. 23. f. 1, 2 (skull). 



Inhab. Van Diemen's Land. 



18. Delphinus dnhins. 



Beak of skull depressed, like D. Ddphis, but rather shorter ; the 

 teeth small and sharp, ^, thin, pointed.

I found three skulls under this name in the Paris Museum. 



1. "D. dubius, Cm. n. 10." (Mus. Paris.) 



SkuU : length (in inches and lines) 15-3, of beak 10-0, width at 

 notch 2-9, at middle of beak 1-7 ; teeth ff or ff ; palate flat, rather 

 convex ; lower jaw flat, obliquely in front and keeled in front beneath. 



2. "D. dubius, Cuv. n.2." (Mus. Paris.) 



Skull : length 16-6, of beak 10-0, of teeth-line 8-6, width at notch 

 3-8, at middle of beak 1-7| ; teeth fj or ^^ , small, hooked ; palate 

 flat, rather convex ; beak tapering in front, reflexed before the notch ; 

 intermaxUlaries rather convex; triangle extending rather in front 

 of the teeth-line, rugose in front. 



3. «D. dubius. Cm. n. 7." (Mus. Paris.) 



Skull, from the Cape de Verd : length 16-0, of beak 9-4, of teeth- 

 line 7-6, width at notch 3-7|, at middle of beak 1-4 ; teeth ||-|f ; 

 triangle scarcely extended in front of the teeth-line ; palate flat ; 

 lower jaw oblique, compressed and flat on the sides, rather turned iip 

 at the tip ; intermaxillaries convex behind ; nose tapering in front. 



This last is perhaps B. frontalis (Dussum. Cuv. R. A. i. 288 ; 

 Pueheran, Eev. & Mag. Zool. 1856, 449). 



" Black, belly white, with a lead-coloured band from angle of 

 mouth to pectoral. 



" Inhab. Cape Verd." 



M. Pueheran observes, from the examination of the bones, that 

 he believes that D. frontalis differs more from D. duMus than from 

 B. frcenatus. In the skulls of all the three specimens the palate is 

 flat ; but in B. frontalis the beak is longer than in B. dubius, and the 

 anterior groove of the intermaxillaries is more open and more pro- 

 minent. The skull of B. frcenatus resembles that of B. dubius in 

 the length of the beak. (See I. c. pp. 459, 460.) 



Belphinus dubivs. — This skuU differs from that of B. Belpliis, as 

 Cuvier has observed, by the appearance of the vomer in a longitu- 

 diual space on the palate between the maxUlaries and premaxiUaries. 

 The palatal prominence formed by the palatine bone is broader and 

 phorter, and the grooves on each side are shallower and much
