LAGENORHYNCITUS CRUCIGER. 91 



iu6ridioiiale,'' uuder the uaine of Delphliim cruolger (and after close ex- 

 aiainatiou I fiud uo reason to believe otherwise), there can be no doubt 

 that this species is the same as the L. clancidus of Gray, described in 

 1849. 



With these skulls must also be associated two other specimens, No. 

 a304:l, of the Paris Museum, labeled L. latlfrons (a name whicli I have 

 been unable to hud in the literature), and No. 3027, of the Royal College 

 of Surgeons. 



In all these specimens the " triangle" is more or less elevated, and is flat 

 and slightly or not at all rugose. The intermaxilhe are flat and nearly 

 horizontal, and are not twisted into a vertical position at the distal ex- 

 tremity. The temporal fossai are full ovals in the Paris specimens, 

 but in the type of L. clancidus the anterior side is straight, so that the 

 fossa? present the appearance of half ovals. The pterygoids are short 

 but wide; they touch the median line. The normal dental formula is 

 probably |4f^i though the teeth in the specimens themselves present 

 the variations in number common to all the toothed whales. 



It has been the fashion, since the time of F. Cuvier at least, to seri- 

 ously consider the identity of the D. cruciger of Quoy and Gaimard and 

 the i>. hivitfatus of Lesson, species which were " viis en mer et desshies 

 a distance.^'' D'Orbigny fell into this error (though hesitatingly) in 

 adopting- Quoy and Gaimard's name for the animal which he captured 

 and of which he sent the skull to Paris. He thereby produced confusion 

 in the nomenclature. The misstep of the French explorers was not that 

 they made drawings of animals which they only saw at a distance, but 

 that they introduced them into their narrative under special scientific 

 names. Considering that such names have no validity, I hold that 

 d'Orbiguy and Gervais's binomial is the proper one to apply to the 

 species in question. 



It is not to be denied, however, that much iuterest frequently attaches 

 to such representations as have been referred to. 



Malm, in his account of the specimens of Cetaceans in the Swedish 

 Museums* describes a skeleton and skin of this species obtained by 

 Captain Warngre at Cape Horn. 



The skull is a little smaller than that of the type of L. cruciger, but 

 agrees with it perfectly in proportions (see table below). The vertebral 

 formula is as follows : C. 7 ; D. 13 ; L. 22 ; Ca. 29 ; total 71. For a full 

 account of this individual the reader is referred to Malm's original 

 article.
