brasiliensis represents the adult of the 8i>ecies, Jlaviventris or dispilurus younger speci- 
mens, and subligarius those still younger. In the type of brasiliensis the head is con- 
siderably less slender than in svMigarius. This is probably a matter of age. This 
species reaches but a small size, none of the known specimens being six inches in 
length. 
As all known specimens of subligarius have thirteen soft dorsal rays, and all otfla- 
viventris examined have twelve, we let them stand for the present as distinct species. 
84. SERRANUS FLAVIVENTRIS. 
Buies flaviventris, Cuv. & Val., Hist. Nat. Poiss., HI, 113, 1829 (Brazil) ; Gunther, I, 267 (copied). 
Ceniropristis hrasiliensis Bvieovit de Barneville, “ Eevue Zoologique, 1847, 131” (Brazil); Gunther, I, 
85, 1859 (St. Helena). 
Serranus brasiliensis Jordan, Proc. U. S. Nat. Mus., 1886, 533 (from Brisout de Barneville’s type). 
Centropristis dispilurus Jordan, Proc. U. S. Nat. Mus., 1886, 27 (Beaufort, N. C.). 
Habitat . — Brazilian fauna. Trinidad to St. Helena. 
Etymology. — Flavus, yellow ; venter, belly. 
For a discussion of the relation of this species to the preceding, see our remarks 
on 8. subligarius. 
The only specimen of this form which we have seen is the type of 0. brasiliensis 
in the museum at Paris. 
85. SERRANUS ANNULARIS. 
Centropristis annularis Gunther, Shore Fishes, Challenger, 1880, 6, pi. I, fig. C (Pernambuco). 
Habitat.— Coast of Brazil. 
Etymology. — Annularis, ringed. 
This species is known from a short description and a figure of a very young in- 
dividual about 2 inches long. It is probnbly a valid species — not the young of Serra- 
nus flaviventris. 
86. SERRANUS ATROBRANCHUS. 
Centropristis atrohranchus Cuv. & Val., Hist. Nat. Poiss., Ill, 45, 1829 (Brazil); Gunther, I, 1859, 86 
(copied). 
Serranus atrohranchus Jordan, Proc. U. S. Nat. Mus., 1886, 532 (examination of original type). 
Habitat . — Coast of Brazil. 
Etymology. — Ater, black ; branchia, gill {iSpay^^a, gills). 
Only the original type of this strongly marked species is yet known. It was 
collected in Brazil by Delalande, and from it our description was taken. 
87. SERRANUS iEQUIDENS. 
Serranus cequidens Gilbert, Proc. U. S. Nat. Mus., 1890 (west coast of Mexico). 
Habitat . — Pacific coast of tropical America. 
Etymology. — ^quus, equal j dens, tooth. 
This species is known from its type, 7 inches long, dredged by the Albatross at 
Station 2996, off the west coast of Mexico.
