region. Priscacara of Cope, well known by beautifully preserved ma- 

 terials from the Green River Eocene of Wyoming, was considered 

 by Regan to be a Centrarchid, but Haseman^ has more recently re- 

 viewed the whole matter, and decides that it is an ancestral Cichlid. 

 In the Antilles we have no less than six species or races of Cichlasoraa 

 (subgenus Para'petenia) living to-day in Cuba, but apparently no 

 Cichlids whatever in the other islands. Do the Cuban fishes represent 

 an invasion from the south in comparatively recent times, or are they 

 the remains of a once widely distributed Antillean Cichlid fauna? 

 The fossil would suggest the latter alternative. It may be described 

 as follows: 



CICHLASOMA WOGDRINGI, new species. 



D. XIV. 10 or 11. A. IV. 10. Base of ventral distinctly (about 

 5 mm.) before level of beginning of dorsal; body shaped practically 

 as in C. tetracanthus Cuvier and Valenciennes (not nearly so deep 

 as in C. nigricans) ; lower jaw somewhat protruding (as in G. nigri- 

 cans) ; scales quadrate, a little over 2 mm. broad, with 7 to 14 basal 

 radii, and in the apical field fine ctenoid elements arranged in decus- 

 sating series. The scales are of a generalized Cichlid type similar 

 to those of Ghaetobrancho'psis oceUarls from Brazil. 



Measurements in mm. : Diameter of orbit, 7.5 ; orbit to end of 

 upper jaw, 14; orbit to end of lower jaw, about 16; length of spinous 

 dorsal, 21 ; of soft dorsal, about 9 ; length of posterior dorsal spines, 

 about 9; length of soif dorsal rays, over 10 (ends lost) ; vertebrae 

 in region of soft dorsal, 3 in about 4.4; longest (posterior) anal 

 spines, about 10.5; soft anal rays, over 21 (from a fragment which 

 seems to have come from a rather larger specimen) ; tip of lower 

 jaw to base of anal, 46; base of ventral to base of anal, about 20; 

 depth of body at level of ventral, 26.6 ; depth of body at about end 

 of soft dorsal, 12.3.
