FISHES FROM JAVA— BEAN AND WEED. 



597 



We are informed that there are many small mountain streams flow- 

 ing into the ba}"- and it is probable that these fish were taken from one 

 of these. 



Head, 3i; depth, 4; snout, 5^; eye, 3^; D. V-I, 8; A. Ill, 8; scales 

 26-20 in horizontal scries, the specimens being in such condition that 

 it is practically impossible to make an accurate count. Teeth in a 

 vilUform patch in each jaw, tlie outer row considerably enlarged. 

 Tlie teeth in the inner rows are so small that they can not be detected 

 by the use of a dissecting needle but are plainly visible under the 

 microscope. Looking directly down on their ends they look like 

 minute papillae. Papillae of similar appearance are visible in all parts 

 of the roof of the mouth of the cotype, being especially crowded on the 

 head of the vomer. The teeth of the outer row are strong, conical, 

 abruptly recurved and, perhaps, slightly flattened at the tip. In 

 Agonostomus monticola the teeth in the jaws are all recurved, with.

the tip flattened, spoon-shaped, bicuspid or tricuspid. A careful 

 inspection will show all types in the same jaw. 



Mouth very small, oblique, the lower jaw strongly projecting. The 

 maxillary does not reach front of eye. 



Caudal rounded; soft dorsal opposite anal and similar to it but 

 with slightly shorter base. 



Scales ctenoid, a single row of teeth on the edge of each. In 

 Agonostomus monticola there are from three to six rows of fine teeth 

 on the outer edge of each scale. An unidentified specimen of Joturus 

 has the entire exposed surface of the scale closely covered with fairly 

 strong teeth. 



This species differs from all other species of Agonostomus of which 

 we can find any descrii)tion in the small number of scales. The 

 mouth, also, is smaller and directed more upward than in others. 

 The teeth are apparently larger than A. monticola.
