those from the Mediterranean. The differences are such as might re- 

 sult from the habitat or i^hice of attachment of the shells. All the 

 Cjilifornian specimens have the larger valve flat, with faint ridges radi- 

 ating from the umbo and becoming obsolete before reaching the mar- 

 gin. The haemal (or dorsal) valve is convex, and the foramen is often 

 anteriorly angulated, though sometimes round. In all the specimens 

 the part of the foramen included in the haemal valve is larger than that 

 included in the neural valve. The 'apoi)hyses are similar to those of 

 Mediterranean specimens. I have from the Caribbean Sea a specimen 

 similarly radiated, and for this form perhaps we may apply the vari- 

 etal name radiafa. 



The special interest attaching to these little brachiopods arises from 

 the fact that this is the first time they have been reported from the 

 Pacific. The San Diego specimens were evidently from the beach ;^ 

 though perfect, they were a little bleached. The single specimen from 

 Todos Santos Bay, though dry, contained the remains of the soft part«.

NOTES ON A COLLECTION OP FISHES FROM FLORIDA, TATITH DE- 

 SCRIPTIONS OF NEW OR LITTLE KNOWN SPECIES. 



By O. r. HAIT. 



The fishes forming the subject of the present paper were contained in 

 a small collection made in Florida and sent to me by Messrs. H. T. Mann 

 and D. M. Davison. A part of the collection was made in Western 

 Florida, at Chafiiu, on the Yellow Water Eiver,and atWestville, near the 

 Choctawhatchee River; but the greater part in the eastern portion of 

 the State, principally at Saint Augustine. The work was done during 

 the month of April of the present year and under very unfavorable cir- 

 cumstances. However, in this paper I describe Gohionellus sniaragdus 

 (C. & V.) Gid,, obtained for the first time on our coast ; Zygonectes 

 nottii Ag., not before identified since it was originally described ; Z. 

 aurogiittatus, and Etheostoma ( Ulocentra) davisoni, which are believed 

 to be new species. Notes on Mugil alhula L. and Lahidesthes sicculus 

 Cope are incorporated. 



1. GobionelluB smaragdus (C. & V.) Grd. 



Among the fishes collected at Saint Augustine there occurs a species 

 of Goby that must be placed under Giiard's genus Gohionellus. The 

 single specimen which was captured having been submitted to Prof. 

 D. S. Jordan's inspection, has been identified by him as the Gobiiis sma- 

 ragdus of Cuvier and Valenciennes. Dr. Gunther in his " Catalogue of 

 the Fishes of the British Museum" gives the name of this species without 

 any description except that it is related to Gohius lanceolatus. As it
