GILBERT AND STARKS — FISHES OF PANAMA BAY 



79 



The maxillary is shorter, 2| to 2.V in head (2 to 2i in C. latns). The preorbital is 

 wider, in the narrowest part two-thirds the diameter of the eye (half eye in C. latus)- 

 The snout is longer, from 2;^ to 3 in head (3| to 3| in 0. latu»). The gill-rakers are 

 more numerous, 4+17 or 18 (4+ 14 or 15 in 0. latus). It has 1 or 2 more soft 

 rays in the dorsal and anal, 22 or 23 dorsal rays, 18 anal rays (20 or 21 dorsal rays, 

 and IG or 17 anal rays in C. latus). One of the Mazatlan specimens is deeper than 

 any specimen we have seen of 0. latus, the others are of the same depth. 



The figure of C. medusicola given by Jordan (1895 6, plate 34), shows the 

 characters of this species very well, except that the preorbital is not wide enough. 

 In the original description, the number of the dorsal spines, gill-rakers, and lateral 

 plates is wrongly given. The first dorsal has 8 spines, the plates to the bend in the 

 lateral line number from 36 to 38.

144. Gnathaaodon speciosus {Fov.sImI). 



Appearing infrequently; on two occasions many large ones were brought to 

 market. Our five specimens all have 19 rays in the dorsal and 10 in the anal. 



145. Citula dorsalis {Gill). 



Frequently brought to market. We preserved seven specimens from 24 to 

 36 cm. in length. To the description given by Jordan and Evermann (1896, p. 930), 

 we make the following additions and corrections, based upon our material.
