the conier of the mouth. Head very flatly depressed above the 

 eyes, and unusually broad at the snout ; in fact, in this species the 

 snout is flatter than iu any other. In the dentition of the cranial 

 bones it resembles the preceding series. That which readily dis- 

 tinguishes it from Cantori and mowa is the dorsal originating half 

 an inch before the anus. 



Colour of the upper aspect, dark olive-green, with a yellowish 

 edging to the dorsal fin. Under aspect, especially the anal fin, 

 lighter. 



Malabar [M. Dussumier). 



Total length, 17-32 in. Length of tail, 10-05 in. To the eye, 

 0-47 in. To the corner of the mouth, 0-71 in. To the pectoral, 

 2-36 in. To the dorsal, 7-09 in. Length of the pectoral, 0-63 in.

Kesembles moica; but is distinguished from it by its higher 

 body, broader snout, and shorter and more rounded pectoral fin, 

 which latter is comprised three and a half times in the length of 

 the head, as measured from the point of the snout to the gill-open- 

 ing, or root of the fin. It has a higher body than A. Bleekeri.

This eel is proportionally a more slender species than labrosa (No. 

 93), and its lips, which have the same structure, are less thick and 

 large. Its profile is depi'essed, or slightly concave, before the eye, and 

 its snout rounded at the end. The eye is moderately large for an 

 Anguilla, and is placed over the angle of the mouth. The anus is 

 before the middle of the fish ; and the distance between it and the 

 gill-opening falls a little short of one-third of the whole length of 

 the fish. The dorsal commences about the eighth of an inch before 

 the vent, in the specimen here described, which is equal to a fifth 

 or sixth part of the vertical height there. Minute delicate scales, 

 arranged in the same lattice-work way as in labrosa, cover the entire 

 integument of the body, head, and fins, the individual scales being 

 oblong, oval, and more obtuse at one end ; but not tapering so much 

 towards the apex as in that species. Under the microscope the 

 scales appear to be entire at the edges, and their disks show con-
