Body is elongate, cylindrical; no pectoral fins. The 4 speci- 

 mens of this species, secured at Tubuai Id., of the Austral group, 

 form a series which show no structural differences, 3 and in which 

 the color markings intergrade perfectly.

 ing color markings: In spirits, color dark brown, shading into 

 black on the posterior half of the body; the body covered with 

 minute white dots, like piu points, yellow in life, none of the dots 

 are as large as the head of a pin, these dots very numerous on the 

 anterior third of body and head, but gradually decreasing in num- 

 ber posteriorly, until on the posterior half of the body they are few 

 and widely scattered; belly and throat yellowish white, being 

 powdered with yellowish dots; in addition to the above there is on 

 the anterior half of the body a number of round, indistinct black 

 spots the size of eye, these show a tendency to form imperfect ver- 

 tical, baud-like arrangement; fins colored similar to body, caudal 

 with a narow white margin. 



No. 763 B. M., a female, 10 in. long, is colored and marked
