UELPIIINUS LONGIROSTRIS.

states that the skull wbicli be extracted from the type-skin of D. capensis 

 has a longer beak than any other Delphinus in the collection, but he 

 does not specify whether absolute or relative length is intended and 

 does not giv^e the number of teetli. 



The skull No. a30G5, which I believe to be thstypeof D. longirostris, 

 is certainly different from that of D. delphis. TLe skull is 49.5"" long, 

 the beak being G7.9 per cent, of this length, a proportion not reached 

 hy nuy akixWs 0^ D. delphis which I have examined. It is also much 

 narrower across the orbits, and the teeth, as already stated, are more 

 numerous, viz, ^^. The temporal fossae are large and rounded, the 

 ])terygoids very narrow and sharply keeled. The palatine grooves are 

 very deep, the intermaxilhii are very high near the notch, and are 

 rounded. The specimen does not appear to be old. I did not find 

 any other which I thought specifically identical with it.
