21. Crotophaga ani (Linn.). "Merle Corbeau," indig. 



22. Coccyzus minor (Gm.) ; Sclater, P. Z. S. 18/0, p. 166. 

 " Coucou manioc," indig. 



Iris "dark brown." Mr. Semper's specimen agrees with the skin 

 already in my collection from Santa'Lucia. 



23. Tinnunculus sparverius (Linn.). 



The skins of this Kestrel from Santa Lucia have very dark bands 

 on the back and tail, and no chestnut spot on the head'of the male, 

 as in specimens from St. Croix. 



Mr. Semper gives the vernacular name of this bird as " Gre-gree 

 Falaise," and describes the iris as "pale reddish brown." 



24. Butorides virescens (Linn.). "Cayalie," indig. 



This Little Bittern oceurs in St. Croix (Newton, Ibis, 1859, p. 261) 

 and most of the other Antilles, except Trinidad, where B. cyannrus 

 (sive scapularis) comes up to meet it (see Finsch, P. Z. S. 1870, 

 p. 589). 



25. Nycticorax violaceus (Linn.). 



A single skin of a young bird of this rather widely spread species, 

 which likewise occurs in St. Croix (Newton, I. c. p 262). 



As I am expecting to receive further collections of the birds of 

 Santa Lucia, I will defer remarks on the general character of the or- 

 nithology of the island to a future occasion. It may, however, be 

 pointed out that it is quite evident, even from the present small 

 series, that the general facies of the Santa Lucian avifauna closely 

 resembles that of the neighbouring islands Dominica and Martinique. 

 Although we are still very imperfectly acquainted with the birds of 

 these two islands, eleven out of the present list have been recorded 

 as occurring in Martinique, and ten in Dominica. The species 

 peculiar to Santa Lucia (so far as we know at present) are three in 

 number— namely, Cinclocerthia macrorhyncha, Icterus laudabilis, 

 and Myiobius latirostris.
