“probably Cuba,” and the type supposed to be in the M. C. Z. This speci- 
men cannot be found but from the description is evidently a Tantilla, also 
doubtless Central American. 
To return to Leimadophis andreae we may say that it is a common and 
widespread lowland species, apparently more abundant in the region of the 
Cienaga de Zapata than elsewhere. It often burrows underground and is very 
frequently turned out by the plough. It shows these varied types of coloura- 
tion and a range of ventral and subcaudal counts, there being about 133-149 
ventrals and about 85 to 100 pairs of subcaudals. The individuals common 
about the Laguna de Manaté, a brackish lagoon near Guantanamo Bay, are 
larger than those so common about the San Carlos Plantation some miles inland. 
Here they live under the labourers’ houses coming up through the cracks in the 
floors. In the casa vivienda they were often found living in cracks in the wall 
close to the floor and even under the brick floors as well (Ramsden).
