660 Zoology. 



Order PSEUDOSCORPIONES. 



The collection of this order has never been systematically 

 studied, and is not extensive. In addition to specimens from 

 various parts of the world, the dried portion of the collection 

 contains the types of Leach's British species, the type of Chelifer 

 bravaisii, Gerv., and some examples from different parts of England, 

 which were identified by the Rev. O. P. Cambridge. The bulk 

 of the spirit-preserved material is derived from the named species 

 forming part of Keyserling's collection. This consists of various 

 species of Cheliferidse and Gbisiidse from Europe, and the typical 

 or co-typical examples of the Australian species described in the 

 last volume of that author's work, " Die Arachniden Australiens." 



Order OPILIONES. 



The fairly extensive collection of this order is represented by 

 both dried and spirit-preserved material, which has never been 

 systematically worked through and named. In 1833 two species 

 of Gonyleptes were described by G. R. Gray in Griffith's " Animal 

 Kingdom." In 1873 and 1874, Mr. A. G. Butler published a 

 list of the known speciea of Gonyleptidse, determined the Museum 

 material of this family, and described several new species ; and 

 in 1897 Mr. R. I. Pocock worked out the relatively small amount 

 of material of Sironidse and Oncopodidse and named a few new 

 species. 



The large number of GonylepticUe and Cosinetidse, and the 

 Australian species of Assamiidse and Phalangodidse, contained in 

 Keyserling's collection, were determined by W. Sorensen, and in 

 1899 duplicate examples of the species of Sironidse were sent to 

 Dr. H. J. Hansen for examination and identification. 



Order PODOGONA. 



This order is represented by a single specimen of Cryptostemma 

 afzelii, collected by Mr. E. E. Austen at Sierra Leone, and by 

 two examples of G. karscliii, obtained on the Benito River, Congo, 

 by Mr. G. L. Bates. The two species were examined and identi- 

 fied by Dr. H. J. Hansen.
