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

 incline to .the opinion that all will prove to be slight varieties only of 

 M. abhatus, — excepting, of course, the tjnicolob, pancalus and 

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

 other. 



Fam. Gobiidce. 



Genus Eleotris, Gronov. Five species are more or less common- 

 ly brought to the Calcutta fish-bazars. Of these, one — E. maceodon 

 ■ — has minute scales ; two — E. poeocephalus and E. inceeta (n. s.) 

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

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

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



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

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

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

 than in E. btjtjs, (B. H.), a range of eight of them only 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 other 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. cavifeons, nobis, n. s. Affined to E. maceodon, 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 prse-opercle, conspicuously 

 developed, as is described of E. madagascaeiensis. Head one* fourth 



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

 (as it stands in the Histoire des JPoissonsJ , I have not seen his arrangement ; 

 but gather incidentally that Butis stands as the type of one group, and another 

 distinct type of large-scaled species is exemplified by E. CAPEBATA and E. 



BUCCATA.
