for A7iolis homolechis, a species having a pure white dewlap in life and smooth 

 ventrals. On our recent \-isit to the island we found the true A. homolechis 

 near Cienfuegos and Madruga. A comparison at once showed that the series of 

 specimens from Camaguey really represented an undescribed form more closely 

 related to Anolis sagrei than to any other species. Its relationship is so evi- 

 dentlj' with this well-known and widespread form that it is less confusing to 

 point out the differences between these two species than to present a prolix 

 diagnosis. 



Comparing adult males, the frontal ridges of A . grayi are much more nearly 

 parallel than in A. sagrei. In the former species they are separated usually by 

 but a single row of scales or perhaps by two small scales lying side by side. In 

 the latter, however, there are either two or three distinct rows filling in the 

 ovoid area hmited by the ridges. This is the most striking difference. In A. 

 grayi the head is more depressed, giving a very much more flat profile, not so 

 declivous as in A. sagrei. In this species also the ventrals are heavily keeled, 

 while in the new one the keels, while distinct, are far less strongly developed. 

 A less conspicuous distinction is the possession of larger and flatter plates about 

 the occipital scale than are found in A. sagrei. 



The color is similar — the same in alcohol. I remember very distinctly 

 that when these specimens were collected, there was a prominent difference in 

 the dewlap color in life. Most unfortunately I did not realize at that time how 

 valuable a diagnostic feature this color character is. 



I have named this species for my friend, Mr. Robert M. Grey, who is in 

 charge of the Harvard Botanical Station maintained at the Soledad estate near 

 Cienfuegos by the generosity of Mr. Edwin F. Atkins of Boston. 



Anolis bremeri, sp. nov. 



Type: — No. 7,889, M. C. Z. a single adult male, Herredura, Cuba, February, 

 1912, Thomas Barbour, collector. 



This species belongs near A . sagrei, and its allies having keeled ventral scales, 

 but differs in squamation and in having a very large dewlap which is rich deep 

 maroon-l^rown in life, while in A . sagrei it is smaller and orange-red, flecked with 

 gray. 



Adult male. Top of head with two curved frontal ridges which converge 

 anteriorly and inclose a shallow frontal area. Head scales including those of the 

 supraocular disc all strongly keeled. Supraocular semicircles separated by a 

 single row of scales, three of which are elongate and elevated to iorm a short
