the higher mountains. We may reasonably expect a form like 

 gundlachi eventually to turn up in Pinar del Rio. 



The status of sierra-maestrae is in some doubt. It is very close 

 to brevipalmatus and may turn out to be the same. 



There are four groups of Eleutherodactylus in the island of Cuba, 

 and the same four are also found in Hispaniola. 



The auriculatus group is represented by auriculatus in Oriente, 

 and is replaced by eileenae in the mountains of Santa Clara and 

 Pinar del Rio. This seems to be a mountain-loving group of 

 forms. The tiny sonans is found all over the island and is easily 

 distinguished by its size and by its much smaller digital disks and 

 tympanum. The peculiar varians is known definitely only from 

 Soledad. It is an arboreal type and lives in the tallest trees in 

 the old lowland forest, now so largely cleared away. These 

 four species form a group which as a whole is characterized by 

 enlarged digital disks, rugose belly, and short vomerine teeth. 



The dimidiatus group is characterized by smooth skin above 

 and below, by long vomerine series, very feebly developed disks, 

 black cheek patch, and gray or tan color. Members of this 

 series are largely restricted to the mountains, dimidiatus occurring 

 throughout the island, and emiliae, which is quite distinct, being 

 known only from Santa Clara. 



The little varleyi, which has short vomerine series, rugose belly, 

 feebly developed disks, a dorso-lateral glandular fold, and a pec- 

 toral vocal sac, seems rather isolated from the rest and forms a 

 group by itself. 



The majority of the forms, however, are allied to ricordii and 

 agree with it in having rugose dorsum, long vomerine series, 

 belly smooth or feebly rugose, and digital disks feebly developed 

 or restricted to the two outer fingers. 



In Santa Clara the small, short-legged ricordii is found near 

 water in the low country, and in the mountains it is replaced by 

 the longer-legged and differently marked casparii. Always as- 

 sociated with water is the web-footed cuneatus, which is found 

 both in lowland and in mountains. Occupying a similar habitat 

 to that of ricordii and casparii is the large, uniformly shagreened 

 greyi, rather rare in the lowlands and more common in the moun- 

 tains. In the dry forest and common in the lowland and rare 

 in the mountains, is the beautifully colored atkinsi, with its 

 markings of scarlet and black. 



In Pinar del Rio pinar ensis (the varians of Barbour, Stejneger, 

 and Schmidt) replaces greyi, differing from it in rugose belly and 

 slightly different color. Cuneatus, ricordii, and atkinsi are also 

 found in this province. 



In Oriente brevipalmatus replaces greyi, differing in its webbed 

 toes. Gundlachi, with red legs and long warts, may replace 

 casparii^ Cuneatus, ricordii, and atkinsi are also found. The 

 insufficiently known sierra-maestrae is allied to brevipalmatus and 

 to ricordii, distinguished from the former by absence of webs and
