the time they are the size of a pigeon have the bronzed-black 

 scapulars so developed that they look, whilst sitting on their nest, 

 erect on their tarsi, as if they had on cloaks. They were not 

 quarrelsome in their disposition, like the boobies ; frequently one 

 would alight on a neighboring nest, without being disturbed by 

 the owner. The single egg, which is white, is large for the size 

 of the body, pretty uniform in shape ; those picked out of some 

 hundreds, as extremes, measured, the lirst, 69^- X 50 ; the second, 

 QQ X 44j-; the third, 61^ X 45. The intestine of this bird is 

 proportionally still shorter than that of the booby, measuring only 

 .850 in length. The stomach .80 in length ; the division into the 

 proventriculus only marked by the belt of glands, and the diameter 

 of it, as well as of the oesophagus, apparently the same as the 

 stomach. The liver is much smaller than in the booby, the right 

 lobe measuring .036 by .032, and the left .04 by .025. Pancreas 

 not observed ; spleen small. Two small globular caeca .09 from 

 anus. 



Graculus Floridamis. At the Biminis cormorants were very 

 abundant ; nesting on the mangroves, as in Florida. On the 20th 

 of February, in some of the nests the young were nearly fledged, 

 whilst in others the eggs had not been laid. None were seen at 

 any of the other kays. 



PJideton Jiavirostris ? The description of the habits of this 

 bird given in " The Naturalist in Bermuda " is so accurate, as to 

 render a detailed description superfluous. I visited three breed- 

 ing-places. At Long Rock, near Exuma, they breed in holes in 

 the horizontal surface of the rock, as also at Water Kay, one of 

 the Ragged Island Kays ; at Kay Verde, which is situated about 

 thirty miles east of Great Ragged Island, in holes in the perpen- 

 dicular face of the cliffs, and also in the horizontal surface of the 

 rock. Before depositing their eggs, the male and female occupy 

 the same hole, but afterwards only one bird is found in a hole. 

 Both sexes incubate. On the 20th of April, about half of the birds 

 had not commenced laying, and a few of the eggs had been sat 

 on for three or four days ; most of them, however, were freshly 

 laid. They feed from near daylight to about nine o'clock, when 

 they return to their holes, in which they pass the hotter part of 

 the day, again leaving them toward sunset in search of food. 

 They cannot, of course, breed in communities like the tern, as
