BRIEF RECORDS OF CILETECHYLENE VESUVIANA, 

 Newp., AND OTHER MYRIOPODS NEW TO THE 

 BRITISH FAUNA. 



By Richard S. Bagnall, F.L.S. 



(Hope Department of Zoology, University Museum, Oxford.) 



Some years ago Dr. Randell Jackson sent me a collection of 

 Chilopods made by him at Sidmouth, in Devonshire, amongst 

 which were four specimens of a large Geophilid. I recently 

 submitted these to Mr. Edw. Ellingsen, of Kragero, Norway, 

 who reported that he had not seen the species before, suggesting 

 that it might be Chcetechylene vesuviana. Prof. Verhoeff has 

 since seen the specimen, and writes that they are undoubtedly 

 that species. 



Chcetechylene vesuviana (Newp.). 



Geophilus vesuvianus, Newport, Trans. Linn. Society, London, 

 xix. p. 435, 1844. 



The species is described fully by Latzel in his ' Die Myrio- 

 poden Osterr.-Ungar. Monarchic ' on page 201, from which it 

 will be seen that the species differs in many particulars from 

 C. montana, Meinert. 



C. montana rarely exceeds 30 mm. in length by 1*4 mm. in 

 breadth, whilst C. vesuviana measures up to 52 mm. by 2'5 mm. 

 in breadth ; the former possesses 57 to 61 pairs of legs in the 

 female and 55 to 59 in the male ; and the latter 63 to 75 in the 

 female, and 61 to 77 in the male. Other points to note in 

 Latzel's description are as follows : — 



C. VESUVIANA. C. MONTANA. 



Pori anales duo, minimi. Spira- Pori anales evanidi. Spiracula 



cula sat magna, rotunda. Pedes sat parva, rotunda. Pedes 



anales . . . femina tenues, maris anales . . . femina tenues, 



crassissimi. maris incrassati. 



The species was originally described by Newport from the 

 slopes of Vesuvius, and must apparently be classed in that group
