1 36 SERRANUS ÏIGRINUS. 



the 1st midway betweeu veutral- and anal fin ; 



the 2'"i at the beginning of the aual fin; 



the 3'J nearly at the middle of the anal fin; 



the 4^^ between anal- and caudal fin. 



The end of the tail and the beginning of the caudal is of 

 a dark color. Dark, oblong spots, serially arranged in a 

 direction from the root of the pectoral to the lower part 

 of the tail , are placed between the cross-bands. The dark spot 

 betweeu the 3'^ and 5^^ ray of the dorsal fin is very charac- 

 teristical. 



Our specimen has the middle spine on the operculum 

 very well developed , and the caudal fin notched as figured 

 by Bloch, and not truncate as in Cuvier's and Seba's specimen. 



One specimen, very well preserved but somewhat disco- 

 lored by the action of the alcohol. — Cura9ao. 



3. Pomacanthus paru^ Bl. 



One young specimen with 5 distinct cross-bands without 

 white crescents or brown spots (Gthr. Cat. of Fishes. 11. 

 p. 56. C : Pomaeanthus quinquecinctus Cuv.). — Curasao. 



4. Go bill s sopor ator ,C\iY. & Val. 

 Nine specimens from Cura9ao. 



5. Blennius crinitus ^ Cuv. & Val. 



Two specimens (from Curasao) 'with 12 -|- 15 dorsal and 2 

 -}-^ 16 anal rays , with some little filaments above the eye , and 

 a filamentous crest on the nape of the neck. The snout is ob- 

 tuse , with the anterior profile abruptly descending. They both 

 have a somewhat larger tooth between the teeth of the 

 underjaw. 



One of the specimens very clearly shows the spot be- 

 tween the 1^' and the 2"'i dorsal spine , the other specimen 

 is too darkly colored (probably under the action of the al- 

 cohol) to show the dark spot. 



This second specimen has another particularity mentioned 

 by Cuvier and not quoted in Giinther's Cat, of Fishes,
