4, Description of two new Species of Slugs of the Genus 



Lor/i^r^. Parmarion from Bopneo . By Walter E. Collinge, 



F.Z.S., Assistant Lecturer and Demonstrator in Zoology 



aud Comparative Anatomy, Mason College, Birmingham. 



[Received June 2, 1897.] 

 (Plate XLIV.) 



The two new species of Parmarion here described were collected 

 by Mr. A. H. Everett at Lombok, ■ Bo . rn e ^ and forwarded to 

 Mr. Edgar A. Smith, of the British Museum, who has very kindly 

 placed the same in my hands for identification. 



The perfect specimens and dissected parts have been placed in 

 the collection of the British Museum, South Kensington. 



In 1895 I described, in conjunction with Lieut.-Col. H. H. 

 Godwin-Austen, E.E.S.\ a series of forms from Borneo allied to 

 those now received, and I am very pleased to be able to examine 

 further material from this interesting region. 



In the above-mentioned paper we expressed the hope that 

 further material would be obtained from Borneo, in order that our 

 knowledge of the genera Parmarion, Microparmarion, Damuyant'a, 

 &c., might be increased. One of the species here described, 

 P. intermedium, may, I think, be regarded as a connecting hnk 

 between the genus Parmarion and Mia'ojparmarion. 



Parmaeion evebbtti, n. sp. 



ffab. Lombok (2000 ft.), BoPftw (A. H. Everett). 



Shell oval in form, almost flat, amber-coloured ; lines of growth 

 well marked, apex obscure, borders membranaceous, hidden by 

 the mantle. 



Major diam. 16 miUim. ; minor diara. 12 millim. 



Animal (PI. XLIV. fig. 1) greenish grey, head darlt green with light 

 brown portion in mid-dorsal line ; sides of head yellow. Mantle- 

 lobes yellowish brown, with fine dark blue speckles and blotches. 

 Commencing beneath the visceral mass, where the dorsum is flat 

 and very pale yellow in colour, are two dark brown bands, shading 

 posteriorly to black, which pass backwards and slightly downwards, 

 terminating at each side of the caudal mucous pore ; posteriorly 

 the sides of the body are speckled with black. Eugse not promi- 

 nent. Eoot-fringe yellow, with somewhat broad chocolate-coloured 

 lineoles, narrowing and becoming hghter in the anterior region. 

 Eoot-sole divided into median and lateral planes, the former 

 yellow in colour, the latter greenish grey. Caudal mucous pore a 

 vertical slit, not extending to the foot-sole (PI. XLIV. fig. 2). 



Length (in alcohol) 42 millim. 



I have much pleasure in associating with this species the name 

 of Mr. A. H. Everett.
