164 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
Remarks:— No further discussion of this species is necessary in 
view of its similarity to C. cornuta. It may be added, however, that 
Stejneger when writing his Herpetology of Porto Rico, suspected 
the distinction between this species. He had, however, no Haitian 
material for comparison and was further deterred by some notes which 
Giinther (Trans. Zool. soc. Lond., 1882, 11, p. 218, pl. 44) published 
regarding a specimen with no locality which died in the London Zoo 
and to Stejneger it seemed unlikely that a specimen from Mona 
would find its way alive to London. We believe that this specimen 
really came from Mona Island, a possibility by no means so remote 
as Stejneger seemed to think, especially when the rarity of the species 
in Haiti is taken into account. It is not unlikely that the small 
Haitian sailing vessels may even visit Mona purposely, to take 
Iguanas for food. It is also not improbable that such individuals 
may be carried alive to Haiti and thence one may have found its way 
to London. (Cf. Stejneger’s discussion of this specimen, Ann. rept. 
U. S. N. M. for 1902, 1904, p. 671). 
Material examined. 
We have only seen Bowdish’s specimens listed by Stejneger (loc. 
cit.). One of these is now in the M. C. Z., 11145, a paratype, figured.
