This and the former species are very like D. Clymene, but are 

 rather broader and rather more depressed ; the intermaxillaries 

 are rather more convex, especially behind, and form a regular 

 defined front edge to the triangle, which is rough in front, and 

 marked with oblique cross grooves ; while in D. Clymene the tri- 

 angle is furnished with an acute, raised margin on each side in 

 front. 



A skull in Mus. Coll. Surgeons (Delphinus Delphis, Cat. Mus. 

 Coll. Surg.\6\, n. 1117), with the palate convex, not grooved on 

 the side ; intermaxillary and vomer forming part of the palate ; 

 teeth ff. Obtained from the Leverian Museum in 1806. May 

 be another variety.

Prof. Nilsson thinks that D. Doris (Gray), D. pseudodelphis

 elongate, reaching just beyond the tooth-line, rugose. Teeth
