the lateral line; scales on cheeks in about 1 rows, 1 row on subopercle 

 and about 1 on opercle ; scales on breast very small, much smaller than 

 those on opercle; soft rays of vertical fins with accompanying series of 

 scales. Coloration in life: Above dark olivaceous, each scale with the 

 basal half dark olive-brown; sides with or without some silvery luster 

 at bases of scales, forming, when present, faint longitudinal streaks ; head 

 and lower parts of body bright red, especially bright on lower parts of 

 head, the color extending up on the sides for a varying distance; upper 

 jaw and maxillary reddish; upper parts of head dark olivaceous; scales 

 on sides of head without dark spots; a much-interrupted light blue line 

 from middle of preorbital along suborbital, rarely extending behind the 

 orbit, much less distinct than in N. argentiventris, and disappearing in 

 alcohol; cheeks sometimes with bluish spots or lines; inside of mouth 

 red; vertical fins very dark, with more or less reddish; spinous dorsal 

 with a broad median streak of very light slaty blue ; pectorals and ven- 

 trals reddish, the latter with dusky. -Length 2| feet. Guaymas to Panama ; 

 a common food-fish ; here described from the original type from Mazatlan. 

 (Spanish, Colorado, red (colored), in allusion to the common name, Par go 

 Colorado.)

1643. NEOMJ:MS BRACHYPTERTJS (Cope). 



Head 2f; depth 3. D. X, 12; A. Ill, 8; scales 8-51-X, 47 pores. Form 

 of N. griseus. Maxillary 2 in head, reaching to past front of eye. 

 Canines very small, developed in upper jaw only; tongue with an 

 oval patch of teeth ; vomer with a A-shaped patch of teeth, there being a 

 short backward projection on the median line; eye rather small, 4f in 

 head. Gill rakers few, arranged as in N. griseus. Scales above lateral 

 line arranged in very oblique series; 2 bands of small scales on temporal 

 region. Anal fin low, its longest rays 2f in head; second anal spine about 

 as long as third, 3^ in head ; caudal little forked, its longest rays 1 in 

 head; pectoral fin short, If in head. Color in spirits, olivaceous, with 

 silvery luster below; rows of obscure dusky spots along the scales on 

 sides and yellowish oblique streaks above the lateral line; fins rather 

 dark, the caudal not pale ; no black lateral spot. The above account is 

 taken from Professor Cope's original type in the museum of the Philadel- 

 phia Academy of Sciences. The species is allied to N. griseus, although 

 apparently distinct from that species and from all others known to us. In 

 its technical characters it approaches most closely to N. synagris, near 

 which species it is convenient to place it in our analytical key. If we 

 suppose the type of N. amMguns to be a hybrid, synagris -\-cliry <surus, we may 

 suspect N. brachypterus to represent a hybrid of griseus and synagris. The 

 evidence in the latter case is less striking than in the former. Bahama 

 Islands; only the type known, (fipaxvs, short; rtrepor, fin.)
