listed from Mindanao should be regarded as distinct from C. 

 lineatus, and perhaps joined to this species. 



The color markings on the head are very different from those 

 in Cyclocorus lineatus. I collected only the two specimens. 



There is a single young specimen in the collection of the 

 Bureau of Science, without locality data, which agrees with 

 the type in general details. It differs slightly in color and in 

 that there is a distinct band, between the eyes, connected with 

 the nuchal spot by an irregularly edged line; the second chin 

 shields are shorter than the anterior; two labials enter the 

 eye, and there are but seven upper labials; ventrals, 130; sub- 

 caudals, 59 ; the median dark stripe is bordered by two broad 

 lighter areas. #

In my treatment of this species I apparently confused certain 

 specimens of Cyclocorus lineatus with C. nuchalis sp. nov., the 

 species herein described. The young specimen mentioned 17 is 

 undoubtedly a specimen of the latter species, as are probably 

 certain others listed in the table; 18 at least, if not identical, 

 I believe they must represent a third species characterized by 

 the temporal formula 1 + 2, the three lower labials touching 

 the chin shields, the three labials entering the eye, and the 

 tail being longer than in C. lineatus. They are probably more 

 closely related to C. nuchalis than to C. lineatus. 



Unfortunately, the specimens are in the Carnegie Museum, 

 and at present not available to me for study. In consequence 

 I hesitate to name the eastern Mindanao specimens. 



The characteristic marking on the head of true Cyclocorus 

 lineatus takes the form of a line from the frontal to the neck 

 that is widened between the eyes and forks into three indis- 

 tinct branches which continue as distinct or broken lines to 

 the tip of the snout; the nuchal band is a V- or a U-shaped 

 mark which crosses the median line five or six scales behind 

 the parietals, and the branches run forward' to ^e postenor 

 temporals where they are joined E^W^** 



at the eye. The light line i
