which it is based is not stated and no figure is offered. The species 

 mentioned last is rather inadequately described, but it was figured. 

 The length of the single specimen upon which the description and 

 figure were based was given as 30 mm. The dift'erences among the 

 three species as determined from descriptions and in part from the 

 figure of S. garthi are set forth in the parallel comparison offered. 

 ^. falarae seems to be unique in the very low broad head. 



atrilabiatus

 day (according to fig- 

 ure). 



None of fin rays with 

 filaments (according 

 to figure). 



Body without cross

 a little more than half 

 the length to base of 

 caudal.

 fourths length of eye.
