526 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
Subfamily VII.—BORIDIIN-. 
XXX. BORIDIA. 
Boridia Cuy. & Val., v, 154, 1830 (grossidens). 
Type: Boridia grossidens Cuyv. & Val. 
Ktymology: Unexplained; possibly from #6¢ and eidos. 
This genus is based on a single species once brought from Brazil, 
but not seen by any recent collector. It is certainly very different from 
any other known fish. It resembles a Yenichthys with the teeth of a 
Calamus, Bleeker places it near Hoplopagrus, which is certainly not 
its natural position. 
ANALYSIS OF SPECIES OF BORIDIA, 
a. Body rather elongate, covered with moderate scales, which are ranged in series 
parallel with the lateral line; mouth small, the maxillary reaching front of 
eye; teeth all blunt and molar, in about three rows in each jaw, the front teeth 
enlarged; eye rather large; preorbital very narrow; nostril small, near eye; 
dorsal fin divided to base, the first and second spines very short, the third 
longest, about } head; soft dorsal and anal low; second anal spine longer and 
stronger than third, but still short; caudal well forked; pectorals quite short, 
shorter than ventrals; soft fins scaleless; depth about equal to length of head 
and about 4 in body; D. x1-1, 13; A. 1, 11; color nearly plain, scales dotted

131. BORIDIA GROSSIDENS. 
Boridia grossidens Cuy. & Val., v, 154, pl. 114, 1830 (Brazil). 
Habitat: Coast of Brazil. 
Etymology: Grossus, thick; dens, tooth. 
This species is known from Cuvier’s description of a single indi- 
vidual, 14 inches long, brought from Brazil by De Lalande. 
Subfamily VIII.—_MAZNINZ, 
XXXI. MANA. 
Meenas Klein, 1749 (nonbinomial). 
Mena Cuvier, Régne Animal, ed. 11, 1828 (mena). 
Mena, Bleeker, Systema Percarum Revisum, 1875, 273 (mena). 
Type: Sparus mena Gmelin. 
Etymology: paws, an old name of some small fish. 
This genus is very closely related to the next, with which it is united 
by Dr. Bleeker, the chief difference being in the presence of rudi- 
mentary vomerine teeth in Mens. Two species are commonly recog- 
nized, besides two doubtful ones, Mena vomerina Cuv. & Val. and Mena 
usculum Cuv. & Vai. All belong to the Mediterranean fauna.
