(E. arminjoniana? similis, sed subtus fuliginosa, et pedibus omnino nigris 

 distinguenda. 



This Fulmar was discovered during the voyage of the " Magenta," and found 

 abundantly by Professor Giglioli in January, 1868, in the neighbourhood of South 

 Trinidad Island, where it was also observed by Dr. E. A. Wilson on the " Discovery," 

 and Mr. M. J. NicoU on the " Valhalla." 



The bird is of dull plumage, and was compared by its original describers to 

 (E. macroptera, to which it bears a general resemblance, but differs in having a white 

 base to the inner web of the first primary, and was, on that account, placed by Salvin 

 in a separate section of the genus (Estrelata. It is also allied to (E. arminjoniana, 

 but may be distinguished by its entirely black tarsi and toes. 



Professor Giglioli points out that (E. trinitatis is, moreover, a smaller bird than CE. 

 macroptera, with wings proportionately longer, and the bill decidedly smaller and 

 weaker, in addition to many other minor points of difference. Dr. Wilson, who 

 visited South Trinidad Island on September 13th, 1901, and obtained eggs, but no 

 young birds, states that (E. trinitatis was found breeding in small colonies, apart from, 

 and much higher up on the ledges and cliffs than its white-breasted ally (E. arminjoniana. 

 In January, 1905, Mr. Nicoll obtained both young and old birds, but reported that 

 (E. trinitatis was not nearly so abundant as (E. arminjoniana, and was only met with 

 on the higher parts of the island.
