of the .skulls wbicb I exiuiiiued in the Oxford, Paris, and Leyden Mii- 

 seuius, and also of tlie. tyi)e skin of the species which is in the British 

 Museum. The dimensions of this latter specimen are as follows:

of Good Hope. 



Meters. 



Total length 1.092 



Extremity of beak to coruer of mouth 0.155 



Extremity of beak to eye 0. 157 



Extremity of beak to blowhole 0. 158 



Extremity of beak to anterior base of pectoral 0. 2r)7 



Extremity of beak to anterior base of dorsal 0. 51G 



Length of base of dorsal 0. 178 



Vertical height of dorsal 0. 082 



Length of pectoral from the anterior base 0. 145 



Breadth of flukes 0.247 



Greatest width of pectoral 0. 056 



The beak is uot sharply defined. The teeth are small and round. 

 At 5.1'"' from the extremity of the mandible the distance between the 

 teeth of opposite sides is J:.G'='". 



A cast of the head of this specimen was recently received by the Na- 

 tional Museum through the liberality of Professor Flower. 



Another stufted skin ism the museum of Leyden. The form i's very 

 similar to that of Fhocaiaa. The dorsal, however, is more sharply tri- 

 angular. The forehead is somewhat concave (this may be due to dry- 

 ing). The color is black throughout, except a rather broad band of 

 white, which starts about 8'"' posterior to the dorsal fin and somewhat 

 below the middle of the side and runs obliquely downward, becoming 

 merged in a second white area which occupies the center of the belly. 

 Another similar but smaller band appears below and behind the first 

 and is also confluent with the white of the belly. This specimen is 

 presumably one of the " mehrere vollstiindige Hiiute" mentioned by 

 Sohlegel in the Ahhandlunijoi (p, 31) as received from the Cape of Good 

 Hope. 



In one of the young skeletons at Leyden I find the v^ertebraj two 

 more than the number given by Professor Flower. The formula, ac- 

 cording to my notes, is as follows : C. 7, D. 13, L. and Ca. 47 = 67. 

 This skeleton, as mounted, is 125*^'" in length. The atlas and axis only 

 are united. The seventh cervical vertebra has a superior transverse 

 l)rocess like the transverse process of a dorsal. A superior trans- 

 verse process is present also in the sixth cervical, but it is not so large. 

 The transverse processes become obsolete at the forty-seventh vertebra, 

 the neural arches at the fiftieth vertebra. The lumbar neural spines are 

 sickle-shaped. The scapula is high, with a short, broad, and incurved 

 acromion ; thecoracoid aboutequ;ils the acromion in length and is broad- 

 ened distally. The scapula is 8.9"'" high, ll.S"^"' long. The first six
