LVTII. — A Contribution to our Knoioledge of the Oligochceta of 

 Travancore. By Dr. LuiGl COGNETTI DE Martiis, Torino, 

 K. Museo Zoologico. 



[Plate XIII.] 



The present paper is the result of tlie examination of a 

 collection belonging to the British Museum and entrusted to 

 me by Prof. F. J. Bell, who received them from the Tri- 

 vandrum Museum *. 



The first work in which Oligochfetes from Travancore are 

 mentioned is a paper by Miss S. M. Fedarb published in 

 1897 (4). Prof. Dr. W. Michaelsen !ias recently discussed 

 the drilofauna of the entire Indian Empire and adjacent 

 regions in two valuable works (12, 13). From these works 

 it results that nineteen species of earthworms have already 

 been collected in the State of Travancore. 



The collection examined by me contains only one of the 

 species which are contained in Michaelsen's lists, viz. Olyphi- 

 drihis annandalei, Mich. It contains besides four new species 

 and a " peregrine" species, Lamjnto mauritii, Kinb., which 

 has already been collected in other localities of S. India. 



At present our knowledge of the drilofauna of Travancore 

 extends to twenty -four species, as follows : — 



Subfam. Octoch^tin^, 

 Octoclisetus aitkeni {Fedb.).

 proof of consideration in sending me this very interesting collection.
