(including the pectorals) are miriutely speckled : but I considerably 

 incline to the opinión that all will prove to be sligbt varieties only oí' 

 M. armatus, — excepting, of conrse, the unicolor, pancalus and 

 zebrinus, — the last two being again very nearly affined to each 

 otber. 



Fam. Gobiidce. 

 Genus Eleotius, Gronov. Five species aré more or less common- 

 ly brought to the Calcutta fish-hazars. Of these, one — E. macrodon 

 ■ — has minute scales ; two — E. porocephaltjs and E. in certa, (n. s.) 

 — have small scales (and the former is less frequently obtainable than 

 the others) ; and there are two wíth large scales — E. butis, (B s H., 

 v. hwmeralis, Val.), and another which appears to be undescribed : — 

 E, buccata, nobis, n. s. Affined to E. caperata, Cantor, and at 

 once distinguished by having a black spot at base of each pectoral 

 fin, margined and dotted with bright gamboge-yellow. Scales larger 

 than in E. butjs, (B. H.),^a range of eight of them oniy from second 

 dorsal to anal fins. The head very short, as high as broad, with a 

 serrated ridge above each orbit, concave between the orbits and convex 

 anteriorly above the mouth, with prominent scaled cheeks or prse- 

 opercles ; teeth small and uniform. In some specimens a series of 

 dark transverse bands is distinctly traceable ; one of them as broad 

 as the first dorsal is long, the otber being equal to the second dorsal : 

 fins infuscated, more or less mottled, and the lower edged with yel- 

 low ; the first ray of the second dorsal being elongated in some spe- 

 cimens, 



D. 6-10.— A. 9. 

 Length 4 in. By no means a common species.* 

 E. cavterons, nobis, n. s. Affined to E. macrodon, Bleeker, but 

 the scales fully twice as large, all the fins much longer, and a remark- 

 able depression between the eyes ; also the same scaleless line or 

 groove from the eye to the insertion of the pise-opercle, conspicuously 

 developed, as is described of E. madagascakiensis. Head one-fourth 



* Tliough aware that Dr. Bleeker has subdivided the great genus Eleoteis 

 (as it stancls in the Histoire des PoissonsJ, I have not seen his arrangement ; 

 but gather incidentally that Bütis stands as the tjpe of one group, and another 

 distinct type of large-scaled species is exemplified bj E. caperata and E. 



BUCCATA.
