While a few of the chysotug form are found in the Tampa collection, and 

 a few of the cingulatus form with the Welaka lot, they can be easily dis- 

 tinguished. A very few of the cingulatus form have 11 anal rays and a 

 very few of chrysotus 10, but they can be otherwise distinguished. 

 Whereas the females of F. cingulatus have no trace of pearly spots the 

 females of F. chrysotus almost invariably have them. As a rule, the cross 

 bars in the male, F. cingulatus, are narrower and more numerous than in the 

 male of F. chrysotus, though young individuals of the latter do not differ 

 in this respect. In Fundulus cingulatus there are often faint spots on the 

 scales of the back forming longitudinal lines which seem to be absent in 

 F. chrysotus. The teeth in the front row of F. chrysotus are larger than in 

 F. cingulatus. 



Page 658. Garman refers Fundulus guttatus to F. nottii, which is very 

 doubtful, bnt he is right in so referring F. hieroglyphicus. He also refers 

 F. dispar to F. nottii, which is probably wrong. 



Page 658. Fundulus guttatus (Agassiz) can not be separated from Fun- 

 dulus nottii (Agassiz). 



Page 659. Fundulus melapleurus is, as Garman observes, a Gambusia, 

 and should stand as Gambusia melapleura. 



Adinia guatemalensis and A. pachycephala are recklessly referred by Gar- 

 man to the synonymy of Fitndulua parvipinnis. They might just as well 

 have been placed at random under any other species of a totally different 

 fauna. 



Page 660. Before Adinia insert : 



30o(a). APLOCHEILUS, McClelland. 



Snout flat, both jaws much depressed. Bones of mandible firmly united ; 

 upper jaw protractile ; each jaw with a narrow band of villiform teeth. 

 Body oblong, depressed anteriorly, compressed posteriorly. Dorsal fin 

 short, commencing behind the origin of the anal, which is more or -less 

 elongate. Intestinal tract but slightly convoluted ; air bladder present.

Page 662. According to Garman the air bladder is present in Eivnlus. 

 He refers B. marmoratus to the synonymy of R. cylindraceus, which is 

 probably correct. 

 Add the following species :
