Specimen.s from the Havana market (litter from Pensacola specimens as 

 follows : 



Body in M.fournieri more elongate, the depth Sf in length to base of 

 caudal, in a specimen 10 inches long. Dor.sal rays X — 1, 30, A. II, 7. 

 Lateral line with ."54 tubes, the scales in 02 oblique rows; 7 scales in a 

 vertical series from first dorsal spine to lateral line ; or 10 in an oblique 

 series (9 in a vertical series in M. undulatus ; 13 in an oblique series). 

 Dorsal spines higher, the longest 1^ in head; pectoral shorter, If in 

 head. The color is notably ditterent. The short vertical bars exi.st 

 aloug the lateral line in both species, but above these, in M. fournieri^ 

 are very distinct undulating lines, formed of dark centers to the scales, 

 these making continuous dark streaks as wide as the pale inter.spaces. 

 The streaks are distinct on the whole back, fin M. undulatus, the daik 

 spots are fewer and scattered, not forming continuous stripes.) Opercle 

 with a dusky shade. Both dorsals pale, without evident spots, the tips 

 dusky. 



The outer teeth are rather weaker in M.fournieri. The size of the 

 eye and the form of the preopercle are essentially alike in lx>th. 



26. Chromis enchrysurus Jor. &, Gilb. 



27. Platyglossus caudalia (Poey) Glinther. ' 



Our Specimens from Pensacola agree equally well or ill with Julia 

 caudalifi Poe;s', Mem. Cuba, II, 213, JuUh pictus Poey, I.e. 214, and Platy- 

 f/lossus poeyi Steindachner, Ichth. Notiz. VI, 49. It is possible that four 

 closely related species exist, each with a blackish spot behind the eye, 

 and the outer rays of the caudal produced. More probably, the foui* 

 are identical. 



28. Decodon puellaris (Poey) Gunthftr. 



A small specimen, in rather poor condition, from the stomach of a 

 Eed Snapper. This is the first record of this interesting si)ecies from 

 the waters of the United States. 



29. Caulolatilus microps Goode &. Bean. 



A large specimen, agreeing very exactly with the description given 

 by Goode & Bean. The separation of this species from C. chrymps ap- 

 pears questionable, but, until more is known of the latter species, it 

 is best to consider the two as distinct. The small size of the eye in 0. 

 micropx is doubtless due to the very large size of the only specimens 

 examined. 



30. Gobius soporator Cuv. & Val. 



31. loglossus calliurus Bean. 



Specimens in good condition. 



32. Gnathypops mystacinus sp. nov. 



Head 3^^^ in length f.j| to tip of caudal) ; depth ^ (of). D. 23or24; 

 A. 11. Lat. 1. with about o4 tubes; 100 scales between gill opening 

 and caudal. Length of type 3^ inches.
