138 POECILIA VANDEPüLLI. 



Length of the largest male , measured with caudal fin 

 31 m.m. 



Many specimens were collected in Curasao. 



I dedicate this species to Mr. J. R H. Neervoort van de 

 Poll, the Zoologist of the Expedition, to whom the Leyden 

 Museum is indebted for this interesting collection. 



7. Poerilia VandepoUi, var. arubensis, v. L. d. J. 

 (PI. 2, fig. 6—10). 



Agrees with the former in the number of finrays , the 

 arrangement and insertion of the teeth (see fig, 7 — 10), 

 the number of scales, and the form of the intromittent 

 organ in the males, but differs in the proportions of the 

 different parts of the body and in the color. The proportion 

 between height and length is in this variety as one to 

 three and a half without caudal fin, or as one to four 

 and a half with the caudal fin. The height of the narrow- 

 est part of the tail is two thirds of the total height of the 

 body. Anal fin in the females somewhat more advanced 

 than in the former species and opposite to the dorsal fin. 



Color brown , yellowish brown on the belly. A dark spot 

 on the head behind the interorbital space , continued in a 

 line which runs up to the beginning of "the dorsal fin. Dark 

 reticulation as in the former , but lateral line nearly invi- 

 sible. Most of the specimens have 6 or 7 shadowy cross- 

 bands on the tail. Dorsal and caudal fin with black lines 

 and spots. 



Total length of the largest female 57 m.ra. A female 

 with embryos measured 50 m.ra. 



Total lencfth of the largest male 36 m.m. 



Many specimens were captured in Aruba. 



8. Muraena eaten at a, Bl. 

 One specimen from Cura9ao. 



9. Cheilic hthy s psittacus, Bl. 8chn. 

 Five specimens were captured at Paramaribo. Length
