147. Gobius encaeomus Jor. & Gilb. 



One small specimen taken with the seine in a shallow bay. 



Light green, with five diffnse spots of darker green on sides, the 

 posterior one most conspicious ; pectorals, both dorsals, and caudal 

 edged above with pale orange; ventrals mostly black, edged with paler; 

 anal dark; a conspicious dusky shoulder-spot; maxillary reaching to 

 below middle of eye ; caudal about half longer than head. Lat. 1. about 

 30. 



This little specimen ai)pears to be identical with that described by us 

 from Charleston under the name of Gobiiis eiicceomns. The species is 

 allied to G. stigmatiirus, but has a much slenderer body. The number of 

 scales in a lateral series is less than 37, the number originally stated by 

 us. There are about 33 in this specimen. 



148. Gobiosoma bosci (Lac^pede). 



One specimen taken with the seine in a shallow bay. 



Pale olive with darker cross bands formed of dark dots ; a row of 

 dark dots along middle of side; vertical fins all mottled and faintly 

 barred with dark olive ; pectorals and ventrals nearly plain. 



149. Gobiosoma ceuthoecum Jor. & Gilb. 



One specimen found in the cavity of a sponge. 



150. Eleotris smaragdus Cnv. & Val. 



(Erotelis valenciennesi Poey. ) 



Two specimens taken with the seine among algae. 



Color in life very dark ohve, almost black, the coloration formed by 

 dark points, which are especially numerous on head and breast. 



First dorsal olive and black ; second, dusky olive, with about four 

 horizontal blackish streaks ; caudal blackish ; anal olive, soiled with 

 dark points; ventrals pale, with dark points; belly livid; pectorals 

 light orange, with blackish points at base ; some dark points behind 

 eye. 



Cuban specimens are rather paler in color, but are not otherwise 

 different. 



Head, 5J in length; depth, 10 to 12. D. VI-1, 10; A. 1, 9 ; Lat. 1. 

 about 100. 



This species differs very strikingly from Eleotris gyrinus in the ex- 

 treme slenderness of its body. It is also strictly a marine species. On 

 account of these peculiarities Professor Poey has made it the type of a 

 distinct genus, Erotelis. 



BLENNIIDiE. 



151. Cremnobates marmoratus Steindachner. 



Eather common ; several specimens taken with the seine in eel-grass. 



Color in life of varying shades of olive-gray or sand color, with a series 



of whitish blotches on head and along sides ; markings on dorsal and
