XX. MENIDIA 51 



The description and figures of Kendall indicate very well the 

 distinctive features of this form. Among other specimens form Florida 

 in the Field Museum, those from Punta Rossa, Boca Grande, Fort 

 Myers, and Captive Pass may be placed on record.

 Atherina gabonensis Boulenger, Ann. Mag. Nat. Hist. (7). 16, 52, 1906; 



Catalogue Fresh-water Fishes Africa, 4, 76, 1916. 

 Type-locality. — "Gabun River, Gabun Country, West Africa" (presumably an 

 error). 

 Range. — Coast and coastwise streams from New England to South Carolina ; 

 fresh waters of Florida ("atrimentis") and the lower Mississippi Valley 

 (' 'audens"). 



After carefully comparing the paratype of Ischnomembras gabu- 

 nensis, stated to have been taken in West Africa, with specimens of 

 M. B. BERYLLINA, wc have come to the conclusion that the two are 

 identical. The type-locality of Ischonomembras gabunensis is very 

 probably incorrect. Dr. Boulenger's reference of gabunensis to Athe- 

 rina, as well as his altering of the spelling of the word was, of course, 

 unjustified. 



Mr. Nichols in 1911 compared specimens of a Menidia from Moon 

 Lake, Mississippi, with examples of Menidia "gracilis" from Long 

 Island. Being unable to detect specific differences, he regarded audens
