HYPSELEOTRIS 39 



Dorsal VI, 1-9; anal I, 9. 



The body is compressed, its belly convex, its snout pointed, and its 

 mouth very small. 



The greatest height, which is at the anus, is five times in the length; 

 this is also the measure of the head and the caudal. The thickness is 

 not more than half the height. The upper and lower lines of the profile 

 are almost straight and meet at an acute angle to form the snout. The 

 eye is more than a fourth of the length of the head ; it is less than an eye in 

 diameter from tip of the snout, and the mouth is not even that long. The 

 teeth are as fine as velvet. The dorsals are but little more than half the 

 height of the body. 



The genital lobule is large, square, and notched. The scales are large; 

 one cannot count more than twenty-six or twenty-eight between the gill 

 and the caudal, and nine or ten from the back to the belly, wider than 

 long, finely ciliate, with fifteen fanlike rays which are visible at the 

 margin. 



In alcohol this little fish is uniform tawny, with a blackish spot at the 

 top of the pectoral base, upon the dorsals traces of brown leave round 

 transparent spots. There are also traces of brown upon the caudal. [Cu- 

 vier and Valenciennes] 



I have seen no specimens of this species, but Jordan and Scale 

 placed here "seven specimens in good condition," collected by 

 Dr. Bashford Dean on the southern coast of Negros. It is 

 known positively only from the Island of Bourbon, or Reunion, 

 in the Indian Ocean and, in the absence of authentic material 

 with which to make comparison, I doubt its occurrence in the 

 Philippines. 



9. HYPSELEOTRIS BIPARTITA cp. nov. 



PLATE 3, PIG. 1 



Bicol name, maringyan. 



Dorsal VI, 1-8 or 9 ; anal I, 10 ; there are 27 scales in a longi- 

 tudinal series, 8 in a transverse series, and 15 before the first 

 dorsal. 



The body much compressed, pointed anteriorly, the dorsal and 

 ventral profiles much arched, the depth 3.36 to 3.64 times, the 

 head 3.42 to 3.67 times in the length; the short truncate snout 

 f the length of eye, 4.4 to 4.75 in head ; the eyes large, circular, 

 lateral, 2.7 to 3.5 times in head, the interorbital equal to snout ; 

 the mouth strongly oblique, the chin projecting boldly, the pos- 

 terior angle of maxillary considerably in advance of eye; the 

 least depth of caudal peduncle a trifle more than twice in its 

 own length and 2.2 times in the length of head; fourth spine 

 of first dorsal highest, 1.46 to 1.9 times in head; second dorsal 

 usually higher, the middle rays longest, or sometimes the pos- 

 terior rays as long, but not reaching caudal when depressed,
