■6 Uiiizcrsity of Michigan 



single faded specimen. Peters' four fresh examples show 

 that the species is not extinct on that island, as Schmidt sup- 

 posed, but, nevertheless, is very rare. Peters got a fine series 

 of topot)-pes of Cope's crythrops from St. Eustatius. Unex- 

 pectedly, they prove to be exactly the same as the Nevis indi- 

 viduals. Erythroccphala from St. Kitts, according to Peters 

 now almost extinct, is represented in the M. C. Z. by the fine 

 series collected by Gannan. This form is really doubtfully 

 distinct from A. crythrops, and I am almost inclined to con- 

 sider crythrops and nevisana both synonyms of erythrocephala, 

 except for the fact that the latter reaches or reached an enor- 

 mously greater size. The rows of ventral plates are the same 

 in number. The type of coloration is similar. The supratem- 

 poral scales in erythroccphala, however, are more enlarged 

 over a larger area. Thus, perhaps, it is more conservative to 

 consider them distinct. 



Amciva garmani Barbour 

 Peters got a tine series of this form which was previously 

 known from the unique type. It is still abundant upon 

 Anguilla and conspicuously distinct. 



Atnciva griswoldi Barbour 

 Specimens from Barbuda collected by my kind friend, ^Ir. 

 Forrest, Health Ofificer at Antigua, are indistinguishable from 

 the three individuals from the latter island upon which I 

 originally based this well-defined form. 



Alsophis cineretis Garman 

 Peters caught two snakes on the isle of Anguilla which 

 agree well with Garman's types of this species, which came 

 from both Anguilla and St. Barts, the rows of scales about 

 the middle of the bodv being 21 in each case.
