FISHES OF SINALOA. 457 



128. Lutianus aratus (Giinther). Pargo Raizero. 



This beautiful species is not very abundant about Maz- 

 atlan, specimens being only occasionally taken. It rarely 

 reaches five pounds in weight. It is generally distributed 

 along the coast, having been recorded from Punta Arenas 

 by Gilbert, and from Chiapam and Panama by Giinther. 



Dark green, the dark stripes on sides dark brown, the 

 interspaces yellowish white; belly coppery red; soine 

 bluish on cheek; pectoral maroon red; ventrals salmon 

 red, the first ray white; anal creamy red; caudal dark 

 red, blackish towards tip; dorsals dusky; throat silvery. 



129. Rabirubia inermis (Peters). Plate xxxix. 



The original type of this species in the museum at Ber- 

 lin was said to have been brought from Mazatlan. A 

 single specimen from Panama is in the museum of Stan- 

 ford University. In this species the supra-occipital crest 

 is continued forward on the head to the ethmoid region, 

 as in the genus Ocyiirus. This character widely separates 

 inermis from the genus Lutianus. The genus Rahiruhia 

 Jordan & Fesler, of which it is the type, is separated 

 from Ocyurus chiefly by the small number of the gill- 

 rakers. 



Family H^:MULID^. 



130. Haemulon sexfasciatum Gill. Roncador Alme- 



JERO. 



This species reaches a larger size than any other of the 

 group, none that were found by us being less than two feet 

 in length. It is not very common, living mainly about 

 the islands. It was obtained by Peters and Gilbert at 

 Mazatlan, and ranges from Cape San Lucas to Panama.
