MINNOWS GAMBUSIA AFFINIS AND CYPRINODON VAKJEGATUS. 15 



indicate that the following species, common in this vicinity, also 

 produce more than one and perhaps several sets of eggs during a 

 single season: Lucania parva (Baird and Girard); Fundulus Jietero- 

 clitus (Linnaeus); Fundulus majalis (Walbaum); Fundulus ocellaris 

 (Jordan and Gilbert) ; Fundulus lucise (Baird and Girard) ; Menidia 

 beryllina (Cope); and Menidia menidia (Linnaeus). 



SUMMARY. 



1. Cyprinodon variegafus inhabits shallow, brackish ponds and 

 ascends fresh-water streams. Stragglers occur in strictly salt water. 



2. Its principal food consists of vegetable matter, but it probably 

 feeds also on many kinds of animal life. In captivity it is very fero- 

 cious and attacks and eats its own kind. 



3. In the Beaufort region this fish spawns from March till October, 

 producing eggs at intervals of varying length. Periods of 10 days or 

 a month may intervene between occasions of spawning or eggs may 

 be deposited daily for a considerable period.
