Nine specimens: Los Indios. 



Only two of these are adults in full black glossy plumage, neither 

 of which, however, although taken in the breeding season, show any 

 sign whatever of lateral crests. One specimen is abnormal in possess- 

 ing /oi^r/ee?? rectrices. 



Cormorants of this species are common all along the coast and about 

 the outlying cays; in fact, it is in such situations one of the most abun- 

 dant and characteristic water-birds. It breeds in colonies at certain 

 points, the nests being built in the mangroves at a low elevation, and 

 composed merely of a few sticks. Two eggs are the usual comple- 

 ment; they are dull bluish green in color, with rough, chalky shells. 

 The species seems to have an extended breeding season, eggs and downy 

 young having been found at a colony in Bird Island, in Siguanea Bay, 

 at such widely separated dates as October 18 and April 16. x\t 

 another colony, in a lagoon south of Los Indios, eggs were secured on 

 October 7, and a month later downy young, possibly two weeks old. 

 The island of Morrillo del Diablo, on the north coast, ofT Punta del 

 Colombo, is another favorite resort of this species. Although partial 

 to the salt water, individuals occasionally ascend the rivers for a little 

 distance, one having been shot on January 21 on the Los Indios River, 

 three miles from its mouth. 



It is possible that some of Mr. Read's records above quoted may 

 refer to the following species. 



5. Phalacrocorax vigua mexicanus (Brandt). Mexican Cormorant. 



Phalacrocorax vigua mexicana {sic) Bangs & Zappey, Am. Nat., XXXIX, 1905, 185 

 (Pasadita, May; meas.; crit.). 



One specimen: Bibijagua. 



The only one observed by Mr. Link was shot near the coast at 

 Bibijagua on July 4. Mr. Zappey secured a specimen at Pasadita 

 in May. These two occurrences are at present the only certain records
