Count Berlepsch has lately separated this Tyrant on the 
ground that it “ differs from true E. martinica of the 
Windward Islands in being much paler and more uniform 
greyish-brown (less mottled) on the upper parts.” He says 
also, “ in colour they agree with E. riisii from St. Thomas 
and Curasao, but have the large measurements of E. 
martinica .” 
I have only three specimens from the Grand Cayman, 
but I have carefully examined a fine series collected by 
Dr. Bowdler Sharpe and Mr. Nicoll, while I have compared 
them with examples from St. Thomas in the British Muse jam 
and my owm collection, and they appear so similar that with 
all regard to such an authority as Count Berlepsch it appears 
to me that it would have been better to have referred this 
form to E. martinica riisii , which I venture to do. My 
examples from St. Thomas certainly give me the impression 
of being slightly smaller than examples from the Grand 
Cayman, but when measurements are taken the differences 
are very slight indeed. 
I notice that Mr. Ridgw^ay ( £ Birds of North and Middle 
America,’ part iv. pp. 428, 429) has included examples of 
E. m. riisii with true E . martinica; but the former bird is 
constantly and uniformly very much paler, and is also 
noticeably smaller, than examples from Dominica, Martinique, 
St. Lucia, and St. Vincent. 
From a geological point of view this form, E. m. riisii, 
ought to be found in Porto Rico, Culebra, St. Thomas, 
St. John, and the whole of the Virgin Islands, which are all 
situated on the same submarine elevation. 
With the form or forms which are found in the happy
