152 FIELD COLUMBIAN MUSEUM ZOOLOGY, VOL. VII. 



We list here a small collection of fishes received from Sr. Diocle- 

 siano Chaves of the National Museum of Nicaragua. A few of these 

 are from Lake Managua, the others from Lago de Asososca and Lago 

 de Guila. The former lake contains fresh water and is reported by 

 Mr. Chaves to be very good to drink. He also states that the fishes 

 from this lake are very good to eat, though the species are few. The 

 red mojarra he says soon loses its color when taken from the water 

 and turns white. Lago de Guila is on the Peninsula of Chiltepe, its 

 water is slightly saline.

Cichlasoma citrinellum (Gunther). MOJARRA. 



The specimens of this species lately received from Nicaragua, 

 show the same ranges of variation as those collected by myself and 

 treated of in a former paper. These were sent under different local 

 or common names. Those of the ordinary coloration were called 

 "mojarra." The specimens which had the spaces between the dark 

 bars the whitest were either "red banded or white banded mojarras." 

 The very dark specirnens were called black mojarras. Some speci- 

 mens are slender, the distance from origin of soft dorsal to origin of 

 soft anal being quite narrow. This species appears to be very abun- 

 dant in all lakes in western Nicaragua where fishes are found
