247. Sigmurus vermicularis (Giiniher). 



Frequently brought into the market, where we collected nine specimens. 



Head from 3j^^y to 3]^ in length. Eye 5] to 5i in head; snout 3^^ to 4; length 

 of third dorsal spine 1-J to 1|; interorbital (bone only) 4| to 5. The dorsal formula 

 is as follows: In one specimen IX, I, 27; in four specimens X, I, 27; in four speci- 

 mens X, I, 26. The anal is constantly II, 8. 



248. Sciaena deliciosa (Tschudi). 



According to Jordan and Eigenmann (1889, p. 406), a few specimens of this 

 species, said to have been taken at Panama, are in the Museum of Comparative 

 Zoology at Cambridge, Mass. There are no other references to the occurrence of 

 this Peruvian species at Panama, and the record is in need of verification. 



249. Micropogon altipianis Gilnther. 



CORBINA LUNA. 



Head 3|', to 3j in length; depth 3i to 34. Eye 6 to 6i times in head; snout projecting 

 beyond the mouth for a distance equaling one-fourth eye. Snout 3^ in head. Anterior nostril very 

 small, circular, with a narrow membranous border, widened posteriorly to form a short flap. Posterior 

 nostril obliquely elliptical, its greatest diameter one-third eye. Ma.xillary reaching vertical from front 

 or middle of pupil, 2^ in head. Anterior prema.xillary teeth of the outer row noticeably larger than 

 those behind them. Usually four pairs of slender mandibular barbels. Upper preopercular serrae very 

 small, increasing in size toward the angle. At the angle, separated from these by a wide interval, is 

 a very strong spine directed downv\ard and backward, below « hich is a similar but shorter spine 

 directed more obliquely downward. The gill-rakers are very short, the longest two-fifths the hori- 

 zontal diameter of the pupil, 15 or 16 present on the horizontal limb of the arch. 



The dorsal fin contains constantly 11 spines, the last longer than the one preceding. In eight 

 specimens the soft rays number 20, 21, 21, 21, 21, 21, 22, 22. The spinous dorsal is very high, the 

 third spine extending to base of first or second ray of soft dorsal; its length is contained i^ to 14 times
