Fourteen, 47 to 82 mm. 



Cichlasoma maculicauda Regan.

Bufo marinus (Linne). 



Two, 43 to 52 mm., from snout tip to vent. 



Bufo typhonius (Linne).

 Eleutherodactylus nubilus (Giinther). 



Two examples, 13 to 28 mm. from snout tip to vent. 



Anolis trochilus Cope. 



Four examples, 111 to 125 mm. in total length. 



Corythophanes cristatus (Merrem). 



One, 240 mm. 



Enyalioides heterolepis (Bocourt). 



One found around rocks near a stream. Length 212 mm. 



Ameiva ruthveni Barbour and Noble. 



This is represented by one example, 283 mm. long. It differs in 

 several respects from the original account. As there is a group of 

 five anterior supraoculars, with the second largest, the frontal is in 

 contact with the second, third, fourth, and very slightly the fifth, 

 supraoculars. No intercalated pair of scales between outer pair 

 of large occipitals and frontoparietals. The two posterior supra- 

 oculars are separated from the superciliaries by narrow wedges of 

 granules, in three or four rows behind. About ten large scales in 

 middle of chin, posteriorly one enlarged twice size of any others. 

 From frontal, down middle of back and tail anteriorly, narrow pale 

 streak. Length 283 mm. 



Apparently very closely related to Ameiva j 'estiva, of which I have 

 compared examples from Colombia and Nicaragua, which agree with 

 my Port Limon example.
