pores along medial edge of dentaiy, anteriormost about K of distance 

 along pore, posterior beneath end of maxillary: 1 small pore sometimes 

 present lateral to middle pore of this series; 1 pore above angular; 2 

 on posterior margin of preopercle, and sometimes another above, and 

 in front of, dorsalmost preopercular pore. The pore system is well 

 illustrated in the figure given with the original description of this 

 species (Torre y Huerta, 1930). One difference is that the Bahaman 

 material lacks the pore on the posterior surface of the angular, as 

 shown on the holotype. 



Lateral line system along body variable and complex, consisting 

 basically of 2 rows of papillae: one with about 35 papillae originating 

 over opercle and extending posteriorly almost to tail in line between 

 midline of fish and dorsal profile; the other, with about 25 papillae, 

 beginning slightly ahead of level of vent and, after an irregular be- 

 ginning, proceeding posteriorly almost to tail in straight line between 

 midline of fish and ventral profile of fish. In addition to these 2 

 basic lines (illustrated on the figure of the holotype), there are a 

 profusion of other papillae whose distribution will not be described 

 in detail. Suffice it to say that some are distributed virtually at 

 random, some are in short series above or below the main lines, some 

 are in short rows in the midline of the fish. 



Papillae also scattered about on head, as are very small dermal 

 filaments; however, no rugose areas on head. 



Dentition and sex: In two specimens a band of granular teeth on 

 premaxillary, another on dentary. Head of vomer carrying 2 large 

 bony knobs, each with patch of granular teeth, each patch connected 

 by narrow line of short teeth. Three other specimens with bands 

 of granular teeth noted above and, in addition, with irregular 

 single row of larger conical teeth located lateral to granular row on 

 premaxillaries and medial to granular row on dentaries. A few of 

 vomerine teeth also slightly enlarged. Specimens with granular teeth 

 with only a small, fleshy flap over genital area. Other 3 with promi- 

 nent, stiffened hoods; at least 1, UP 1151, with well-developed testes. 



Head spines: Short, sharp spine piercing skin at upper angle of 

 opercle. One specimen with several short spines at lower angle of 

 opercle. Two short, sharp spines at lower angle of preopercle. 

 Ventrally projecting premaxillary spine prominent, angular project- 

 ing downward as prominent blunt spine. 



Vertebrae and ribs: Neural spines 5-13 or 14 short and broad but 

 becoming progressively more elongate and narrower; their tips trun- 

 cate. Neural spines on subsequent centra needle-like. Centrum 

 7 with free ribs, although rudiments of parapophysis visible on X-ray 

 photograph of 1 specimen. Centra 8, 9, and 10-12 with ribs at ends 

 of parapophyses, subsequent centra lacking pleural ribs. Centra
