male, U.S.N.M. no. 81239, is as follows : Ground color dull indigo-blue 

 above lightening to glaucous blue beneath, with coarse reticulations of 

 brick-red on the sides and back ; posterior part of head indigo-blue, 

 with the snout and frontal portions coral-red to rufous ; the malar and 

 labial scales orange chrome to coral-red, with a suggestion of these 

 colors on the chin, which is mostly dull china-blue ; nuchal spines pale 

 olive-buif slightly tinged with flesh color ; dorsal spines mostly light 

 coral-red. with occasionally a dull china-blue one ; tail light indigo, a 

 few of the anterior caudal spines tinged with pink; upper surfaces of 

 fore and hind feet black. The other adult specimens are similar in 

 coloration, although they are not so bright in hue. A young specimen, 

 no. 81242, is uniformly dull indigo, without any dorsal crossbands 

 whatever or any indication of a reticulated pattern. 



The largest specimen, no. 81239, measures 270 mm from snout to 

 end of body; unfortunately its tail is reproduced. A smaller lizard 

 measuring 215 mm in head and body has a complete tail 360 mm long. 

 The young specimen already referred to is 140 mm from snout to 

 vent. 



We have been told repeatedly upon inquiring about iguanas that we would 

 find them on Fish Cay, and so we did. We obtained a dozen good-sized speci- 

 mens among the bushes by snaring them with string nooses on the end of a 

 stick. We were considerably surprised, howe\er, when we took them from our 

 bag on board the ship to find that four of them were dead ; evidently they have 

 a way of committing suicide, similar to the ones we collected in the Gulf of 

 California on Angel de la Guardia Island (Sauromalus hispidus now in the 

 American Museum of Natural History). We have saved the eight remaining 

 and hope to carry them through alive to Washington. Peters shot four more. 

 The dead specimens I have injected with strong formalin-alcohol mixture and 

 they have been put in alcohol. These iguanas are vegetable feeders. They are 

 fairly tame and persisted in chasing the noose on the end of our sticks, instead of 

 running their heads through them, or letting us place it around their necks. 

 When hard pressed they finally dash into holes that look like huge sand crab 

 burrows, or when near the coast, where there is a hurricane rampart, they seek 

 refuge in the crevices of the rocks.
