the near by mainland. These are the Elaenia which is much more 
like E. martinica subpagana, than it is any of the gray Lesser Antillean 
forms; the Vireosylva caymanensis which is very closely related to 
V. magister of the coast of British Honduras and unlike any West 
Indian form; and the Vireo, which so far as I can see is identical with 
V. crassirostris the bird inhabiting the Bahamas (which are of simi- 
lar formation). This species is so much like V. ochraceus of the 
opposite coasts of Central America and so unlike any of the species 
peculiar to the Greater Antilles;— Cuba, Jamaica, or Porto Rico, 
that there seems no question of its origin. 
The remainder of the Cayman birds have come from either Jamaica 
or Cuba, in some case being still identical with the parent stock, in 
others having differentiated into what may be called island species 
or subspecies according to the degree of change. From Jamaica the 
Caymans have received Leptotila collaris and Icterus bairdi. From 
Cuba the islands have derived the two forms of Amazona peculiar to 
them, Colaptes gundlachi, Centurus caymanensis, Mimocichla coryi, 
two forms of Holoquiscalus, Spindalis salvini, and Melopyrrha taylori; 
probably also Tolmarchus caymanensis, although this species might be 
descended from either 7. caudifasciatus of Cuba or T. jamaicensis of 
Jamaica. 
From the above which discusses every bird peculiar to the Caymans 
it will be seen that I am unable to recognize several forms which have 
been described as species or subspecies peculiar to the islands, and 
these I comment upon at length in the following list. 
At the time of Brown’s visit to Little Cayman and Cayman Brae — 
June and July — the Boobies and Man-o’-War-Birds were not breed- 
ing and all he saw during his stay were occasional birds off shore. 
Besides these and the list of species following he saw and positively 
identified only two species, namely Hydranassa tricolor ruficollis 
(Gosse) and Nyctanassa violacea (Linné). = 
Brown took nests and eggs of a number of the species; these are 
preserved in the Museum of Comparative Zoélogy, and I believe 
some of them have not before been collected. I have marked with 
an asterisk each species of which he secured the nest and eggs; and 
with a dagger the species of which the eggs only were taken. 
As this paper was going to press, an article on the birds of Grand 
Cayman appeared in the Ibis, January 1916, p. 17-35, by T. M. Savage 
English. Mr. English apparently collected no specimens, but based 
all his identifications on living birds observed afield. During his 
three years’ residence in the island he was able to add twelve species
