10. BATRACniD^. 



15. Batrachus tau Liuii. — '•Surpo"; Sea llobiu. 



A. s])eciuieu of this species, Ko. 21,477 (27), corresponds closelj^ in 

 coloration with the southern specimens referred to by Giiuther. 



Other individuals were obtained, which had grown to the size of 12 

 or 15 inches, and which, if coloration were accepted as a mark of specitic 

 rank, would surely be entitled to description as new species. The ground- 

 color is gray or yellowish white, covered with large irregular blotches and 

 small roundish spots of brown. The type of coloration is very diiTorent 

 fiom that described by Giinther from southern specimens in the British 

 Museum. A fidler description of these specimens with measurements 

 will be given hereafter. 



11. GOBIID^. 



16. Gobius soporator Cnv. &. Val. 



A single si^ecimen, No. 22,852, 2^ inches in length, of a species of 

 Gohius, was sent by Mr. Stearns. It is so sliri veiled up from immersion 

 in too strong alcohol that its characters are not very clearly to be made 

 out. It agrees very well with tlie descriptions of Gohius Hoporator, and 

 is very like specimens of that species from the Bermudas, except that 

 the fins are blackish, and, unlike the Bermuda specimens, show no spots. 



17 Eleotris gyrinus Ciiv. tfc Val. 



.\ single specimen, No. 22,85o, of an EJeofris, agrees essentially with 

 the descriptions of E. gyrinus and with specimens sent under this name 

 from Cuba by Professor Poey. 



12. TRIGLID^. 



18. Dactyloptems voUtans (Liuu.) Laf. 



A single specimen, CA inches in length, and measuring between the 

 tip.s of the extended fins 8.1 inches. B. I, IV, I, 8; A. 0; P. 0, 22; V. 7; 

 C. 5, 4. 



In the young, the proportional length of the ]>rc(percular spines is 

 greater than in the adult, equalling the greatest width of the head. 

 The scales upon the flanks are conspicuously carinate, in the first and 

 fourth rows from the abdominal flat surface showing a tendency to form 

 strong ridges upon the sides of the bod>-. The first and second rays of 

 the first dorsal are separated from the other rays of tliis fin, and when 

 Tlie fin is (closed and resting in the dorsal groo>e tlie first ray falls back 

 u])()ii the dorsal surface upon the right-hantl side, the second upon the 

 left emijracing the fin. These rays resemble filaments, and it seems 

 probable tliat they have independent motion, like tLe filaments of 

 Lojyhins. They are never received into tlie dorsal grooAC. The fins are
