GRAMPUS GRISEUS

tiiiued in the same locality, the diagonal lines are much like those 

 represented in Professor Flower's figure. 



The second young individual (No. 2), which is 73 inches long (along 

 the curves), departs in color both from that figured by Professor Flower 

 and that jnst described. The whole head, including the eyes and 

 month, and to the blowhole, the belly, lower half of the tail and under 

 side of the flukes, and pectoral fins are light yellowish, approaching 

 white. On the upper part of the head and on the lower lip the tint ap- 

 proaches lemon yellow. The back and upper side of the flukes and pec- 

 toral ttns are dark gray. On the lips and over the base of the pectoral fin 

 are irregular areas of light brown. 



The contour of the body in this specimen, however, is exactly that of 

 the specimen previously described, and in spite of the difference in color 

 I do not hesitate to assign them to the same species. The dimensions 

 of the two SDCcimens are as follows: 



Measurements. 



Tip of snout to notch of flukes (on the curves) 



'I'i p of snout to eye 



Tip of snout to corner of mouth 



Tip of snout to h;ise of pectoral fin 



Tip of snout to blow-hole 



Tip of snout to dorsal fin 



Lcnjith of pestoral along the center 



AVidth of pectoral (greatest) 



Width of flukes 



Height of dorsal fin (vertical) 



Length of base of dorsal fin 



Both these specimens show the slight extension of the upper jaw 

 over the lower jaw, which is characteristic of this genus as well as 

 of Globiccphahis and Delphmapterus. 



One of the heads referred to is entirely of a lightish-gray color, ex- 

 cept the throat, which is yellowish white. The two remaining heads 

 are not at present accessible. 



Of the four skeletons none, unfortunately, are absolutely complete, 

 nor is the sex noted ; they lack from one to three of the last caudal 

 vertebric. Their formula', with the additions which seem to be neces- 

 sary to restore the original number of vertebra^ are as follows : 



u. n. C. 7 ; D. 12 ; L. & Ca. 49 (? + 1) = 68 (or ? 09). LcDgth as mounted, 9 feet lOf 

 iucLes.

The two mounted skeletons agree very closely with that described by 

 M. Fischer. There are some slight differences in the point at which
