T had tbund a new species. 1 yxas led to that opinion by the 

 number of spines and sott rays in the vertical fins. Jordan ') 

 describes Elassomä evergladei with four spines and 9 oi- 10 

 sott rays in the dorsal and three spines and 5 soft rays in the 

 anal. On my specimens I counted five spines (in one only 4) 

 and 11 or 12 soft rays and the forniula of the anal was III, 

 7. There was thus one spine and 1 or 2 soft rays in the dorsal 

 and 2 soft rays in the anal more than in the typical E. ever- 

 2ladei. I therefore believed just to establish a new subspecies 

 Avith the name »orlandicum» the more as also the color etc. was 

 ditferent. Låter on I found in the literature that Woolman ^) 

 had found in Pemberton creek variations in another direction 

 that is: with the formula III, 8 for the dorsal and IV, 5 for 

 the anal. But in Santa Fé river the specimens were more 

 similar to mine with dorsal IV, 9 — 12 anal III, 5 — 7. Through 

 this the variability of the E. evergladei becomes still more 

 evident.

My largest specimen measured 25 mm. without the caudal, 

 which is rounded not slightly emarginate. WooLMANS figure 

 (1. c. Pl. LIII) has the caudal rounded too. 



In the females the ventrals reach to the anal, in the males 

 the filament from the fourth ray surpasses the spines of the anal. 



Intestinal canal short, no appendices pyloricae.
