In comparing these new species with Barbus ivis Seale and 

 B. palaivanensis Boulenger, certain striking differences of body- 

 proportions are apparent. The length of head in body is much 

 less, the diameter of eye in depth of body is much greater, 

 the depth of head in body is less, the distance from snout to 

 occiput is much less, the length of base of dorsal in body is 

 more, the height of dorsal and of anal in body is more, and 

 the length of pectoral in body is more in B. ivis and B. pala- 

 wanensis than in the two new species here described. 



In these two new species, not only are there three rows of pha- 

 ryngeals as stated by Gunther, 1 but another row was discovered 

 consisting of three pharyngeal teeth, so that the pharyngeals are 

 3-5-3-2 instead of 5-3-2. The extra row of pharyngeals was 

 also found in specimens of Barbus ivis Seale and B. palaivanensis 

 Boulenger. 



Unfortunately, several specimens of the species here described 

 were dissected before the extra pharyngeals were discovered. 

 But because of the fact that they were definitely determined 

 in several specimens and because a part of the pharyngeals 

 of this extra row were seen in several other specimens, there 

 can be no doubt of the existence of the extra row, and it is 

 undoubtedly always present in both of these species. In some 

 of the fishes dissected, as in B. bantolanensis , No. 45, from which 

 the drawing of the pharyngeals was made, these pharyngeals are 

 very minute. The microscope is often necessary to identify them.
