HANSEN AND SORENSEN, THE TARTARIDES. 3 



inclined to think that it is distinct>>; both species are. in 

 reality, male and female of the same species. — In 1888 T. 

 Thorell (Ann. del Museo Civico di Stor. Nat. di Genova, 

 Ser. 2, vol. VI., p. 358) proposed the name Oxopoei for the 

 tribe containing the family Thelyphonoidae, adopting the name 

 Tartarides Cambr. for the othcr tribe; furthermore he discar- 

 ded Nyctalops as preoccupied and proposed the name 

 Schizonotus for the genus. In 1889 Thorell in his »Aracnidi 

 Artrogastri Birmani» (Ibid. Ser. 2, vol. VII.) described two 

 new species on which he established his genus Tripeltis. 

 Thorell' s descriptions are very careful and especially one of 

 them is very detailed; they point out numerous features and 

 characters to be met with in the whole group, but this is 

 natural as the descriptions given by Cambridge of this genus 

 and its two species are proportionately brief , and Thorell had 

 not seen specimens of these forms. — In our paper »The 

 Order Palpigradi Thor. (Koenenia mirabilis Grassi) and its 

 relationship to the other Arachnida» (Entom. Tidskr. Ent. För. 

 Stockholm, Vol. XVIII., 1898, p. 223—240) some remarks on 

 the morphology of the exoskeleton of the Tartarides are 

 produced. 



In the paper »Revision der Uropygi (Thelyphonidae auct.)» 

 (Abhandl. aus dem Gebiete der Naturwiss. herausgeg. vom 

 Xaturw. Verein Hamburg, Vol. XV., 1897) K. Kraepelin fol- 

 lows the classification of Thorell in all respects, produces a 

 moderately detailed characterization of the tribe with its two 

 genera and short descriptions of the four species already 

 mentioned; he had seen typical specimens of all these forms 

 and besides of a fifth (Artacariis liheriensis Cook, »in litt.»)^ 

 but he cancels, certainly incoriectlv, the last-named species 

 as probably identical with one of the forms from Ceylon. 

 This treatise being the main systematic work on the Uropygi, 

 critical remarks on some of the authors statements will be 

 produced below. — In »Das Tierreich», 8. Lief., 1899, K. 

 Kraepelin again deals with all Uropygi, but as to the Tarta- 

 rides his new treatment is only an abstract of his former 

 work, with the exception that instead of the name Tripeltis 

 he introduces Trifhyreus. 



In Proceed. Entom. Soc. Washington, Vol. IV., 1899, O. 

 F. Cook published a paper >>Hubbardia, a new Genus of 

 Pedipalpi'> (pp. 249 — 261 ; Pl. III). This contribution is rather
