completely. The only definite head marking is a black diagonal bar 

 across the temporal region midway between eye and ear. Tliis does 

 not occur in olssoni but is found in every specimen of semilineatus. 

 A series of examples from Constanza will be needed to determine 

 whether these characters are stable and definite, meriting specific 

 separation, or whether they represent an aberrant or hybridized olssoni 

 with some of the semilineatus characters. 



Apparently the paratype of olssoni (A.M.N.H. No. 15300) is cor- 

 rectly^ identified in the original description. The specimen itself is in 

 bad condition. At the time I noted its differences from the type,' I 

 had seen very few individuals of the species and consequently did not 

 estimate its variability. The two examples from Gonave Island do 

 not appear to differ from those found on the mainland at Port-au- 

 Prince and at San Michel du Nord. 



I add Fischer's record of a Cap-Haitien specimen to this species 

 rather than to semilineatus, since I have seen true olssoni from Cap- 

 Haitien, but as yet I have no evidence that semilineatus occurs there.
