fifth again longer ; the eighth to eleventh spines longest, thence gradually 

 decreasing to the next to the last, which is much shorter than the last ; 

 soft dorsal rays considerably higher than the spines, the longest about \ 

 length of head; anal long, not very high, the membrane deeply notched 

 between all but the last 6 rays, which are the highest. Pectorals % length 

 of head; ventrals as long as from snout to edge of preopercle. Belly 

 naked anteriorly; the scales small, cycloid; lateral line complete. Color 

 olivaceous, darker above, much mottled and speckled with clear dark 

 brown; sides with 5 distinct irregular dark-brown bars, extending from 

 base of dorsal to level of lower margin of pectoral, their lower edges con- 

 nected by a vague undulating longitudinal band ; a blackish blotch on 

 occipital region, and black blotches on cheeks, opercles, and before base 

 of pectoral; opercle with several narrow pinkish streaks: head below 

 with narrow streaks formed by series of dark-brown spots ; an interrupted 

 brown bar across lower jaw; belly unspotted; ventrals pale ; other fins all 

 barred with narrow series of dark-brown dots; anal somewhat dusky. 

 Coast of Brazil and the west coast of Mexico; common. Here described 

 from the types of Clinus zonifer. This is the most abundant denizen of 

 the rock pools around Mazatlan, with the single exception of GoUus 

 separator, reaching a length of 3 to 5 inches. We are unable to separate 

 M. zonifer from Mazatlan from Bahia examples of M. delalandi, and take our 

 account from specimens of the former. (Named for Delalande, who col- 

 lected for Cuvier in Brazil.)

2700. MALACOCTENUS VERSICOLOR (Poey). 



Head 3 ; depth 3|. D. XVIII, 12 ; A. 20. Body compressed ; head mod- 

 erate; snout prolonged; pectoral 1| in head; ventral If; eye large, as 

 long as snout, 3| in head ; nostrils not tubular ; mouth small ; maxillary 

 not reaching so far as eye; teeth firm, in 1 row, those above much larger 

 and slightly curved backward; 12 teeth above and 9 below on each 

 side [no teeth on vomer] ; no tentacle over eye; no anal papilla; a comb 

 of filiform tentacles on each side of the neck; head naked; body scaly; 

 lateral line short; dorsal with 2 depressions, the first spine higher than 

 the 4 which follow, the depressions much more marked than in M. varius; 

 pectoral reaching beyond front of anal. Color yellowish brown ; head, 

 trunk, and fins varied with vertical brown bands and large brown spots; 

 ventrals yellowish. On the figure the 5 bands behind the anal cross the 

 body and extend on the vertical fins. Cuba. One specimen known, 53 mm. 

 in length. (Poey.) Apparently very close to M. delalandi, but lacking 

 the orbital tentacle, and, according to Poey, vomerine teeth also, (versi- 

 color, variegated.) 

 Myxodes versicolor,* POEY, Enuraeratio, 131, pi. 5, f. 1, 1875, Cuba. (Coll. Poey.) 



* This species and its affines were referred by Poey to Myxodes, a South American 

 genus allied to Clinus and Giblonsia, but differing from the latter in its uniserial teeth.
