well as on the body, is dark olive brown, lighter brown on 

 tlie sides and yellowish beneatb with small indistinct white 

 markings on the shields. 



Possibly the preceding species also passes through that 

 same stage of development in coloiir; all specimens however 

 being halfgrown, as far as I can judge, it is impossible to 

 decide the matter. Such a variation in colour appears by the 

 fact that on the smallest specimen the white döts on the ven- 

 trals are more numerous and more distinct than in the two 

 other, but the head is rather darker than in these.

Chiorophis carinatus. Spec. nov. 



Among the collections of the museum from the West 

 Africa there are five snakes, belonging to the same species, 

 which I, though with some hesitation, ref er to the genus 

 Chiorophis, although they show some discrepancies from the 

 forms of this genus. The specimens in question differ namely 

 from these in having only 13 rows of scales and possessing 

 a very great number (about 40) maxillary teeth, but in other 

 re.spects they resemble this genus so closely, that I think it 

 most correct to refer them to this one, especially as I have 

 found in the few C/^Zorop /«'.s-specimens in the museum that 

 the maxillary teeth are more than 25, which number Bou- 

 LENGER states as maximum for the genus Chiorophis.
