Dtsci-ijition of a niw Suctorial Millipedf sent front Trinldud l>if 

 Mr. J. H. Hart, of the Royal Botanical Gardens, Trinidiid. By 

 K. I. PococK. 



In my report upou thi> Diplopoda of the West Indies, puldisheU 

 in Joiirn. Linn. Soc, Zool. xxiv., I enumerated on pp. 478-47f) four 

 species of suctorial Millipedes as beinjr known from the West-Indian 

 area. Three of these, belonpin"; to the genus Si/>honophora, were 

 from Cuba and St. Vincent, and the fourth, a iSijJionotus, was from 

 the latter island. No sjiecies had at the time been obtained in 

 Trinidad ; consequently Mr. Hart's recently received consignment 

 of a dozen specimens of a new species of this group was of consider- 

 able interest, the more so since they prove to belong to a genus, 

 SijiJioiiorJiinus, which is new to the Neotropical fauna. 



This species may be called, in honour of its discoverer, 



Sij^honorhinus Hartii, sp. n. 



Colour (in alcohol) a reddish yellow, deeper at the anterior end ; 

 a distinct black band extending along the middle lino of the back 

 throughout the length of the body ; the keels of the segments a little 

 darker than the pale area on each side of the dark median band ; 

 the head reddish brown ; anteiiiur, rostrum, and legs pale yellow. 



Ihad not pyriform, four-sided, being very abruptly narrowed at 

 the base of the rostrum. 



Rostrum slender, elongate, only a little thicker at the base than 

 halfway up, a little more than half the length of the head. 



Antetince thick, rather short, incrassate, the second segment a 

 little longer than the third, fourth, or fifth, and a little longer than 

 wide, the sixth barely thicker than the fifth and not quite twice its 

 length. 



Body wide, the pleura) projecting beyond the tips of the feet, the 

 area of the tergal piece that lies below the keel or poriferous 

 excrescence nearly vertical. The elevated portion of the segments 

 clothed thickly with silky pubescence; the anterior lower part 

 coriaceous in front, granular behind. 



Number of segments variable ; in the type 59, in others 50, &c. 



Length of typo lb"5 niillim., width "2. 



This species may be at once recognized from the Oriental members 

 of the genus by its variegated colouring and longer and thinner 

 rostrum.

This book is usually found bound in twenty-four volumes, with 

 dedicatory titlepages ; but considerable uncertainty has been felt 

 with regard to the actual dates of the species therein described for 

 the first time.
