674 ON NEW FISHES IN THE BRITISH MUSEUM. [Nov. 21, 



with large round brown spots ; trunk with five, tail with six brown 

 cross bands, broader than the interspaces, and the middle ones the 

 broadest ; they extend on the dorsal fin. Dorsal fin with longitu- 

 dinal lines, anal with a darker margin. 



One specimen was sent from Manado by Dr. A. B. Meyer; it is 

 nearly 12 inches long, viz. head 1 inch 1 1 lines, trunk 3 inches 3 lines, 

 and tail 6 inches 9 lines. 



MUR.ENA CHILENSIS. 



Teeth of moderate size, acute ; those of the maxillary and the 

 anterior of the mandible biserial, the others uniserial. The jaws can 

 be shut completely. Snout of moderate length, subconical. Eye 

 small, somewhat nearer to the end of the snout than to the corner 

 of the mouth. Nasal tubes short ; cleft of the mouth of moderate 

 width, its length being less than two fifths of that of the head. Gill- 

 opening narrow. Dorsal fin low. Tail considerably shorter than 

 the body ; the length of the head is nearly one third of that of the 

 trunk. Coffee-brown, irregularly marbled with darker. 



One specimen, 34 inches long (no. 144), from the Godeffroy col- 

 lection. Chile. 



MuR^ENA T^ENIOIDES. 



Dorsal fin elevated, the posterior rays being as high as, or higher 

 than, the body underneath, commencing considerably in advance of 

 the gill-opening. Teeth conical, acute, those of the maxillary in a 

 double series ; the mouth can be shut completely. The length of 

 the anterior nasal tubes less than the vertical diameter of the eye_. 

 Snout obtusely conical, twice as long as the diameter of the eye, 

 which is of moderate size and above the middle of the cleft of the 

 mouth. Gill-opening not much wider than the eye. Tail rather 

 longer than the body ; the length of the head is one fifth of that of 

 the trunk. Body and tail uniform light brownish; dorsal and anal 

 with a white margin. Head with small black dots, more numerous 

 towards the end of the snout. 



One specimen, 15| inches long (no. 53), from the Godeffroy Mu- 

 seum. From Savay. 



Tetrodon pleurostictus. (Plate LXIX. fig. A.) 



The lower side of the tail with a distinct ridge-like fold. The two 

 nasal openings of each side are in a single papilla. The anterior 

 part of the abdomen and sometimes the middle of the back of the 

 trunk with minute spines, the remainder of the fish being entirely 

 smooth. Snout short, its length being less than the width of the 

 interorbital space. The length of the head equals its distance from 

 the dorsal fin. Caudal fin truncate. Upper parts brown ; sides 

 greyish, gradually passing into the white of the lower parts. A 

 series of three black round spots on each side of the body — the first 

 corresponding to the upper posterior corner of the pectoral, the second 

 below the end of the dorsal, and the third on the upper half of the 

 tail, near the base of the caudal.
