Mr. Morrison. D. Californicus Simon, is a very pretty species, a 

 little smaller tha,n pa llipea, more brightly colored and specially dis- 

 tinguished by a series of nine spiny hairs on the internal edge of the 

 metatarsus of each of the fourth feet. It is found in California and 

 Arizona. Mr. Cleveland has found this species near San Diego, un- 

 der a board, near together in small funnel-shaped sand holes, with 

 nothing else near them in the way of life. They were very bellig- 

 erent. A large fulvous species with a broad dark dorsal band on 

 the abdomen, received from California and Arizona, appears to be 

 closely allied tt), if not identical with, D. formidabiliis Simon, des- 

 cribed from Mexico. It is probable that the specimen collected by 

 Captain Marcy, in his Red River expedition, and described by 

 Girard, under the name of Galeodes subulata Say, is the male of 

 this species. The specimen is still preserved in the museum of the 

 Academy of Natural Sciences of Philadelphia, and is quite distinct 

 from the subulata of Say, which is but the male of paUipes. 



A species from Mexico is described by M. Simon under the name 

 of D. (jeiiiculata (C. L. Koch), but it is distinct from the genlculata 

 of Koch. Specimens collected by Parry and Palmer, at San Louis 

 Potosi, Mexico, were probably of this species. I). (Zerbina) (jradlin 

 Koch, from Columbia; D. pnp.cox Koch, D. cinerascen.s Koch and 

 Doesia foi'micarius Koch, from Mexico, referred to DatanwA by M. 

 Simon, are also unknown to me. 



In Cltobls the anterior margin of the cephalic shield is more or 

 less prolonged or curved, the fingers of the falces are nearly similar 

 in form in both sexes, but in the males the fixed finger is furnished 

 with a slender flagellum. C. cubm Lucas, a very beautiful species, 

 — mm. long, of a grayish color, with two longitudinal dark bands 

 on the back, has been collected in Florida by Dr. Stimpson and Mr. 

 Wurdenian. A species which agrees perfectly with the description 

 and figure of G. gerdculata Koch, originally described from South 

 America, has been collected by Mr. Belfrage, in Texas. It is of a 

 fawn color with a broad brownish black band on the back. (J. sal- 

 tatrix Simon, from Mexico, collected by Dr. Palmer, C. limbata 

 Lucas, from Mexico, (one $, in collection of Emerton may be this) 

 and G. morsicans Gervais, from Chili, included in ClM>bis by M. 

 Simon, are unknown to me. 



The genus Munwiucia is very similar to Clcobis^ differing mainly 

 in the arrangement of the teeth on the fingers of the falces. It con- 

 tains but a single species, M. variegata Gervais, from Chili, a small,
