The following species are referred to Congrina: C. aequorea (Gil- 

 bert and Cramer), C. retrotiucta (Jordan and Snyder) C. stimpsoni 

 (Fowler), C. megalops (Fowler), C. odontostomus (Fowler), C. flava 

 (Goode and Bean),C r oosendaali {^&htr and De Beaufort ),C\ nitens 

 (Jordan and Bollman), and C. duhia- (Breder). The figure and de- 

 scription of Pscudoxcnouiystax are so similar to my new species (es- 

 pecially in view of Parr's remarks) that I believe it belongs here. The 

 new species differs from all these in various proportional measure- 

 ments. It is especially close to C. rctrotincta but dift'ers in the shorter 

 preoral length of the snout and in having a distinct black margin the 

 full length of the vertical fins. From C. duhia it is distinguished by 

 the longer trunk, more attenuated tail, and by the shape of the vom- 

 erine patch of teeth.
