ZIPHIUS OBTAINED NEAE DUISTEDIN. 245 



in the proximal and five in the distal row. Probably these authors consider the 

 scaphoid as a trapezium and count the pisiform cartilage in the distal row. Von Haast 

 does not mention the number of phalanges in his specimen. 



The right pelvic bone, as it appeared when freshly cleaned, is shown in Plate XLIX. 

 fig. 7. It has the rib-like form described by Murie ' in Glohiocephalus, but is tipped 

 with cartilage only at its narrow or anterior end. 



3. Teeth. 

 As usual there are two teeth, one at the extremity of each mandibular ramus, and 

 both completely covered, in the entire animal, by the gum. They are in the form of 

 slightly curved hollow cones, 3-5 cm. (1-4 in.) long and 1 cm. (0"4 in.) in diameter at 

 the base. The weight of each is 1"2 grm. (18-5 grains) in the dry state. They are 

 thus considerably smaller than any described by von Haast, the smallest examined by 

 whom was 1'98 inch long and weighed 62 grains. 



4. Alimentary Canal. 



The tongue is short, barely free at the tip, and has the anterior margin rounded and 

 slightly fiinged ; the mucous membrane of the anterior or buccal portion is tough and 

 leathery and devoid of papillae. 



The pharynx and pharyngeal portion of the tongue are plicated longitudinally and 

 beset with small punctiform apertures. 



The stomach (PI. L. fig. 8) does not seem to have been adequately described: it 

 consists of ten well-marked compartments. Shortly after removal the character of the 

 mucous membrane was examined by partly everting the organ ; it was then distended 

 with air and dried, the compartments being finally opened. 



The first compartment is 55 cm. (21-5 in.) in length, and is imperfectly divided into 

 a larger oesophageal or proximal and a smaller distal portion by a transverse constric- 

 tion situated immediately proximad of the opening into the next compartment. The 

 mucous membrane was hard and raised into ridges, reminding one of the reticulum of 

 the sheep's stomach, but having less prominent and less regularly arranged ridges. In 

 the smaller or distal division the ridges were more closely arranged. 



The first compartment opens by a large valvular orifice into the second. The latter 

 is small and wedge-shaped, and lies almost concealed between the first and third com- 

 partments. In the distended condition the septa between the second and the two 

 adjacent compartments are only separated from one another by a distance of 2 cm. 

 The greatest length of this chamber is 9 cm., its breadth 5 cm. Its opening into the 

 third compartment is large and oval. 



The remaining (3rd to 10th) compartments are arranged in a helicine curve measuring 

 140 cm. (55 in.) along the convexity, and having a reflection of the peritoneum attached
