dorsal crest, and fewer siipralahials llian does Ihe Turks Island form. 

 Nevertheless, it is nuicli closer to carinata than it is to nuchalis which 

 has swollen enlarged scales on the snout and hence is at once separahle 

 from the other two forms under discussion. 



We had been told upon inquiry all along Mariguana Cay that Booby Cay 

 had iguanas upon it, and this information was confirmed, for shortly after our 

 arrival we started off a huge fellow who went crashing through the brush and 

 took refuge in a hole, for these iguanas den like rabbits and when pursued slip 

 underground. We had made nooses of wire and tried to catch some of them 

 alive, but the heavy weight of the animals quickly caused my copper wire to 

 untwist at the loop and the old fellow went crashing through the brush scared 

 by this new experience. Nye had a similar experience, only his wire parted at 

 the stick and the iguana carried it off. I am afraid this will be a dead iguana, 

 for I saw him choking. Further efforts to obtain these animals alive resulted 

 in a waste of a great amount of time, and caused us to decide to give up this 

 achievement. Later in the afternoon Chittick and Nye went iguana-hunting and 

 secured four. I had shot one in the morning and we had caught a baby alive, 

 which will give us six specimens for scientific study.

CYCLURA NUCHALIS Barbour and Noble 



Cyclura nuchalis Barbour and Noble, Bull. Mus. Comp. Zool., vol. 60, p. 156, 

 1916. 

 Eleven examples of this interesting species (U.S.N.M. nos. 81234- 

 44) were taken on Fish Cay of the Fortune Island Group on July 11, 

 1930. The number of spines in the dorsal crest ranges between 62 and 

 y2, averaging 67.7. The nuchal crest has 15 to 19 spines, averaging 

 16.7, and these are irregular both in length and in basal width, as 

 Barbour and Noble indicated. The femoral pores are numerous, run- 

 ning from 21 to 28, and averaging 24.7. On the distal part of the tail 

 the verticils are not very distinct, but when they can be seen there are 

 five rows of small scales separating them. The coloration of the adult
