VAIMOSA 149 



28 to 30 millimeters long, collected by H. R. Montalban at Capiz, 

 Panay; three specimens, about the same size, from Iloilo; and 

 twenty from Molo, Iloilo Province, Panay. 



The collection contains eight specimens, 23 to 30 millimeters 

 in length, in atrocious condition, which evidently belong here; 

 they also came from Malabon in 1907. The scales vary from 

 25 to 28, and in the larger ones, which are males, the dorsal 

 spines and posterior dorsal rays are more or less elongated, 

 the spines reaching to the second dorsal and the posterior ray 

 almost touching the base of the caudal; in other respects they 

 are like the types. I also place here seven specimens in vile 

 condition and mostly denuded of scales, collected from Mariri 

 River, San Jose de Buenavista, Antique Province; they are 

 from 25 to 28 millimeters in length. 



I list here also six specimens, 23 to 29 millimeters long, from 

 Molo, Iloilo; they are faded and most of them have lost the 

 characteristic spots on the base of the caudal ; the largest one is 

 a female, distended with eggs, which exude from the swollen 

 genital papilla. 



Rather than call them new I refer here eight specimens from 

 Lake Taal, 12 to 19 millimeters in length; the scales are 26, 

 and there are several black markings not present in the type 

 specimens, including four black spots on the belly along the 

 base of the anal. 



Piapensis, from Piapi Creek, the type locality.

PLATE 11, FIG. 1 



Dorsal VI, 1-7 or 8; anal I, 7; there are 27 to 29 scales in 

 a longitudinal series, 8 or 9 in a transverse series, and 7 or 8 

 before the first dorsal, the anterior one or two larger than the 

 others. 



The body elongate, much compressed laterally, the back strong- 

 ly arched, and highest at base of first dorsal, the depth 4.3 

 to 5 times (in one specimen 5.6) in length; the head moderately 

 convex, 3.4 to 3.65 times in length, its depth | or 0.1 less than 

 its breadth, which is 1.5 to 1.6 times in its own length; the small 

 convex snout round-pointed, 5 to 5.2 times in head; the eyes 

 large, lateral but high up, longer than snout, about 3 to 3.5 

 times in head, very close together, the interorbital width less 

 than the diameter of the small pupil, about 4 to 6 times in eye ; 

 the jaws equal, the mouth of moderate size, oblique, the lips 

 rather broad, thick, the posterior angle of the maxillary extend- 

 ing back to beneath anterior half of eye or front margin of
