146 GOBIES OP THE PHILIPPINES 



brown, the original ground color appearing between as curved 

 bands or rounded spots; a dark crossbar or spots at base of 

 caudal and several black crossbands or rows of black spots upon 

 it, the tip dusky ; the first dorsal more or less dusky, the elong- 

 ated tip of first spine black, and a black spot on upper mar- 

 gin behind third spine ; the second dorsal has two black or dusky 

 crossbands; the anal black, the ventrals black to nearly clear 

 with blackish center, and the pectorals clear or with dusky tips. 



Here described from thirteen specimens, 15.5 to 31.5 milli- 

 meters long, from Lake Taal, Batangas Province, Luzon. They 

 ase closely related to V. dispar (Peters), but the number of 

 scales and the shape of the first dorsal are quite different. The 

 huge mouth and maxillary are a characteristic of both sexes, 

 instead of being confined to the males, as in V. dispar. 



I also discovered in the Bureau of Science collection a female 

 specimen, 26 millimeters long, obtained in Momboc River, Lake 

 Naujan, Mindoro, by A. L. Day. It differs in having 26 scales 

 in longitudinal series, and the color markings of the body have 

 disappeared after twelve years in alcohol. It is uniform reddish 

 brown, with traces of darker markings on the side. The fins 

 are colored as in the types. 



I likewise place here a specimen, 38 millimeters long, collected 

 by me under the wharf at Bungau, Sulu Province. It also has 

 26 scales in longitudinal series, and the head is much narrower 

 than in the other specimens. This is the only marine specimen 

 thus far known to me.

63. VAIMOSA MICROSTOMIA Seale 



Vaimosa microstomia SEALE, Philip. Journ. Sci. , A 4 (1909) 538. 



Dorsal VI, 1-7 ; anal I, 7 ; there are 27 scales in a longitudinal 

 series, 8 in a vertical series, and 7 before the first dorsal. 



The body stout, broader than head, laterally compressed, the 

 upper and lower outlines about equally curved, the depth 3.5, 

 the head 3.8 times in length ; the convex snout bluntly rounded, 

 heavy, projecting beyond mouth, 5.25 times in head; the eye 

 high up, lateral, larger than snout, 3.75 times in head ; the inter- 

 orbital about half an eye diameter in breadth ; the mouth small, 

 inferior, the posterior angle of maxillary under anterior third 

 of eye ; the teeth minute, in a narrow band of three rows in each 

 jaw; the body covered with large ctenoid scales which extend 

 forward on nape to eyes; the opercles covered by nine or ten
