possess both head and tubercle, but the eighth, nhith, and tenth have onlj^ a smgle 

 terminal articular facet. 



The sternum, which consists of five segments, is similar in form to that of 

 semijunctus. The two sides of each segment are united. The posterior emargina- 

 tion of the third segment, and those of both ends of the fourth and fifth segments 

 are small. The scapula and humerus are like those of semijunctus in form. The 

 remaining parts of both pectoral limbs are lacking. 



Without more material, and especially some skeletons of adults, it is difficult 

 to decide what importance should be assigned to the differences observable in the 

 cervical and thoracic vertebra of this young Bering Island specimen. The 

 measurements of the skeleton are included in the table on pages 47 and 48. 



EXTERNAL CHARACTERS. 



The series of photographs (Cat. No. 142579) of an individual obtained in Kiska 

 Harbor, Alaska, is very interesting as affording comparison of what is apparently a 

 specimen of grebnitzkii with the Atlantic form represented in the photograph of 

 the Newport, Rhode Island, specimen. As no part of the Kiska specimen was 

 preserved, it is not possible, of course, to identify it positively with grehnitzkii or 

 even with the genus Ziphius. No one who compares the photographs reproduced 

 in PI. 41, figs. 3 and 4, can, I think, fail to be convinced that both represent animals 

 of the same genus and that the Pacific species (whether grebnitzhii or not) bears the 

 strongest possible resemblance to the Atlantic one. 



Doctor Egbert published the following note on the Kiska specimen in 190.5: 



Early in September a monster dolphin grounded on the beach in Kiska Harbor and was killed. 

 Specific identification has not yet been made. The general color was bluish-gray; length, 18* feet; 

 estimated weight, 3,600 pounds; sex, male. Body was quite regular in shape and rather rotund, the 

 greatest circumference being about midway between dorsal fin and tip of the rather short snout. This 

 dolphin was hauled alongside the ship, stripped of its blubber, and the oil extracted. Some of the flesh 

 was eaten. The oil obtained was of excellent quality. It was particularly desired for use on the wire 

 of the deep-sea sounding machine used aboard the [U. S. Coast Survey steamer] Patterson, a 



The size was about the same as that of the Newport specimen. ^Uthough 

 Doctor Egbert gives the color merely as "bluish gray," the photographs indicate 

 that the belly was white, or whitish, and that there were oval white spots on the 

 sides. As a whole, therefore, the coloration was similar to that of the New Zealand 

 specimens of cavirosiris obtained at Port Cooper and Lyttleton Harbor. 



When compared with the photograph of the Newport specimen (PI. 41, fig. 4) 

 it will be seen that the Kiska photograph represents an animal practically identical in 

 general form, as well as in the general shape of the head, the length and form of the 

 snout, the size and general shape of the pectoral fins. In the photograph of the New- 

 port specimen the flukes are not well seen, but in the Kiska photograph the posterior 

 median convexity peculiar to the ziphioids is clearly represented. The dorsal iin 

 of the Newport specimen appears to be turned somewhat to one side and the tip 

 crumpled, which makes it appear lower and somewhat longer and less pointed than
