CICHLOSOMA (p. 17). 

 1 (a). Cichlosoma zonatum. 



CicMasoma zonatum, Meek^ Proc. Biol. Soc. Washington, xviii. 1905, p. 245 '. 



This species was originally described as having the jaws equal anteriorly, and I suggested (aiiieu, p. '20) that 

 it might be the same as C. guUulatian. Dr. Meek (Publ. Columbian Mus., Zool. vii. 1907, p. 141) has 

 now stated that C. zonatum differs from C. (juttidaium in the smaller and niore inferior mouth ; it is 

 evidently allied to C. eijjeiimanni, differing in the deeper body (depth 2yLj in the length), the lower 

 spinous dorsal (last spine i the length of head), and the fewer soft rays (10 or 11) in the dorsal tin. 



Hab. Mexico, Niltepec in Oaxaca i. 



Cichlosoma maculicauda (p. 19). 



Recorded from Belize by Meek (Publ. Columbian Mus., Zool. vii. 1907, p. 151). 



3 (a). CicMosoma nigritum. 



Clchlasorna nigritum, Meek, Publ. Columbian Mus., Zool. vii. 1907, p. 128. 



Apparently very similar to C. maeulicauda, but the coloration plain dark olivaceous, without a dark spot on 

 the caudal peduncle. 



Hah. Lake Nicaragua. 



Cichlosoma microphthalmus (p. 20). 



To the synonymy add : — 

 Cichlasoma milleri, Meek, Publ. Columbian Mus., Zool. vii. 1907, p. 142. 

 Meek's type is also from the Rio Motagua. 



Cichlosoma pavonaceum (p. 21). 



This sj)ecies appears to resemble Hericlithys cyanoguUatiis in so many respects 

 that it seems probable that it may prove to belong to the genus Ilerichtliys. 



Cichlosoma sieboldii (p. 21). 



Specimens of C. sieboldii from Costa Rica (Pittier) show that it is a ParaneetfOj^>lu>> 

 and is the same as the species described on p. 30 from a single badly preserved 

 example under the name Hericlithys underwoodi. 



22 (a). Cichlosoma alfari. 



Cichlasoma alfari, Meek, Publ. Columbian Mus., Zool. vii. 1907, p. 148. 



Differs from G. halleatwn especially in the lower spinous dorsal, the last spine acarccly more than -5 the lengtli 

 of head. 



Hal). Costa Rica, Turrialba.
