central apex of which scarcely exceeds the lateral points which gradually 

 decrease. During life the fish carries the tail much more erect than 

 is represented in the figures of M. M. Ruppell, Miiller and Henle. 

 The length of the male appendages is less than one-half of the inner 

 margin of the ventral fins. During life this species is distinguished by 

 its beautiful light tint and by its proportions. A solitary young male 

 was taken at Pinang in March 1845. It lived for about two hours in the 

 air. The stomach contained remains of small Crustacea. The length 

 of the intestinal canal slightly exceeded £ of the total length of the fish. 



Gen. Stegostoma, Midler und Henle, 1837. 



Mouth transverse and narrow ; at the upper and lower jaw the inte- 

 guments form two flattened rims, which carry the teeth ; the latter 

 exhibit tripartite laminae ; the centrepiece between the nasal valves is 

 much broader than the valves themselves, and forms a transverse thick 

 rim over the mouth, which above and in front can be covered by this 

 rim. The latter has a rounded free margin in which unite the anterior 

 and posterior surfaces ; the posterior, generally hidden, surface is scaly 

 like the rest. The nasal valves are reduced to skinny hems which 

 laterally enclose the central rim. The nasal valves terminate in a 

 strong cirrus. The lower margin of the nostril has no valve. The 

 folds of the angle of the mouth are short ; the fossets deep. The 

 head is highly arched and rounded. The cleft between the eyelids is 

 very small, transversely oval, with sharp margins. The spiracles are 

 vertical fissures behind the eye. The fifth branchial opening is hid in the 

 fourth ; the third, fourth and fifth appear immediately above the pectoral 

 fins. The anterior dorsal is placed opposite the ventral fins, but 

 extends somewhat in advance ; the posterior dorsal is placed between the 

 ventrals and the anal. The latter is placed immediately in front of the 

 caudal. The latter is nearly throughout of uniform height, with the 

 usual incision before the apex, and it is proportionally very elongated,
