288 PROCEEDINGS OP THE ACADEMY OF [1883. 



very small, short and slender, not numerous ; chin with five pores ; 

 rami of mandible each with a row of slender, inconspicuous 

 barbels along the inner edge ; nostrils round. 



Scales rather large, smooth to the touch, apparently ti'uly 

 cycloid. 



Head 3| in length ; depth 4 ; eye very small, 8^ in head ; inter- 

 orbital space 3^ ; maxillary 2§ ; dorsal rays XI-30 ; dorsal fin 

 low, the soft dorsal highest posteriorly and scaled at base only ; 

 anal small, ending under middle of soft dorsal, its second spine 

 as long as snout, 3f in head; pectoral very long, 2| in body; 

 caudal lanceolate, unequal, its length 3^ in body. 



Color in spirits, light olive, with faint streaks along the rows 

 of scales ; no cross-bands ; pectorals dusky ; other fins plain. 



18. Polycirrhns dumerili Bocourt. 



T3^pe, La Union. 



This species seems to be identical with Genyanemus fasciatus 

 Steindachner (Ichth. Beitr., ii, 31, 1875). The name given by 

 Bocourt has precedence. The genus Polycirr-hus is perhaps 

 worthy of distinction from Genyanemus, having the dorsal spines 

 in normal number (10 instead of 14), the mouth subinferior instead 

 of terminal, the caudal double truncate instead of emarginate, and 

 the gill-rakers very small. Genyanemus peruanus Steind. (1. c, 29) 

 and G. brasilianus Steind. (1. c, Bi ^ Micropoyon ornatiis Gthr.) 

 apparently belong to Polycirrhus. 



19. Menticirrus saxatilis (Bloeh & Schneider) Jordan 



(Johnius saxatilis Bloch & Selineider, Syst. Ichth , 1801, p. 75.) 

 {Scicena nebulosa Mitch., Trans. Lit. and Phil. Soc, 1815, 408.) 



The type of Johnius saxatilis Bloch & Schneider, from New 

 Yoi'k, is still preserved in the museum at Berlin. It is appar- 

 ently identical with the common king-fish, Menticirrus nebulosus 

 (Mitchill) Gill, which species should therefore stand as Menti- 

 cirrus saxatilis. The common names of this species, of the 

 weak fish and the striped bass, have evidently been confused by 

 Schneider. 



Jokni\is carutta, the species taken by Professor Gill as the t3'pe 

 of the genus Johnius, has the preopercle entire, and the mouth 

 inferior. Johnius is apparently not distinguishable from the sub- 

 genus Gorvina, as defined by Jordan & Gilbert (Synopsis Fish. 

 N. A., 1883, p. 932).
