Height 5. 7, about 7 in length with caudal. Head 4. 3, 

 about 5 5 J / 2 in length with caudal, its breadth about 5 / G of 

 its length. Eye 4. 5 6, about thrice in snout, somewhat less 

 than twice in the interorbital space. Lips somewhat swollen, 

 not fringed; barbels minute, subequal, shorter than eye. Origin 

 of dorsal behind middle of snout and root of caudal, corres- 

 ponding to about the 2i g t lateral scale and opposite to inner 

 ray of ventrals, separated by 23 rows of scales from the head. 

 Origin of anal below the 34^ lateral scale, somewhat nearer 

 to end of ventrals than to base of caudal. Ventrals opposite 

 to 1 7 th perforated scale, not reaching anus, slightly shorter 

 than head. Pectorals reaching ventrals, more than one eye 

 diameter longer than head. Caudal equal to head, deeply emar- 

 ginate, lobes pointed, the lower the longer. Scaly, with exception 



i) Through the kindness of Dr. R. GESTRO, Director of the Museo Civico 

 di Geneva, we had the opportunity to study 2 specimens of Helgia modesta 

 Vinciguerra from Burma. They are closely allied to Homaloptera wassinki Blkr. 

 but distinguished at once from this species by the lower number of pectoral 

 rays which is 6.8 and by the slightly emarginate caudal. Miss C. POPTA, Ph. D. 

 has called a specimen from river Mahakam, Borneo, Helgia modesta. It seems 

 us more probable, that it belongs to Homaloptera wassinki Blkr. She gives the 

 number 5.11 for the pectoral rays (one of us has counted 6.11), and gives 

 besides other small differences from Helgia modesta.
