obtained by Mr. Whymper, tbe species found on the moun- 

 tains do not for the most part differ from those of the lowlands. 

 Of the seven species brought back two only are new. Both 

 of these, since they belong to the rare and little-known genus 

 Newporti'a, are of special interest, inasmuch as they throw 

 fresh light upon the specific characters of the genus. The 

 genus bcolopocryptojJSj too, has proved very troublesome to 

 systematists, and all who are interested in the Chilopoda 

 must feel grateful to Mr. Whymper for having preserved so 

 large a number of individuals of Sc. mexicanus, for I have 

 thereby been enabled to draw up with confidence the synonymy 

 of this species as given below.

Otostigma appendicxilatum, Porath, Bih. Sv. Vet. Ak. Handl. iv. p. 23 

 (1876). 



Mr. Whymper obtamed specimens in the valley of Chillo, 

 8500 feet, Machachi, 9800 feet, and on Corazon at an altitude 

 of 12,000 feet. 



De Saussure and Porath have recorded this species from 

 Rio Janeiro, and, in addition to specimens from this locality, 

 Kohlrausch had others from Popayan, in Colombia. This 

 author considered the remarkable appendage on the anal legs 

 to be a monstrosity. It is in reality a sexual character 

 belonging in all probability to the male.

From the localities that Dr. Meinert gives this species is 

 common in the West Indies and Brazil. It appears also to 

 be common in Mexico. In Ecuador it is very abundant, 

 specimens being obtained at Chiquipoquio, on Chimborazo, 

 and on the south side of the mountain at an altitude of 12,000 

 to 13,000 feet, and on the east side at 11,700 feet; at 

 Pichincha, 12,000 feet j at Machachi, 9800 feet; at the
