Oligocliceta of Travancore. 495 



This paper was already in type when I received, by the 

 kindness of Prof. Dr. W. Michaelsen, liis monograph '^ Die 

 Oligochatenfaunadervorderindisch-ceylonischen Region" (13), 

 issued in September, 1910. In the following pages is found 

 a description of Glt/pkidrilus annandahi, Mich., which I 

 wrote before receiving this monograph. My description agrees 

 with that of Michaelsen ; the two descriptions supplement 

 each other. 



Fam. Moniligastridae. 



Drawida fakir, sp. n. (PI. XIII. figs. 1-3.) 



A single immature specimen. 



External characters. — Length 85 mm., greatest thickness 

 3 mm.; number of segments 98. 



Colour uniformly lilac-grey. 



Head prolobous; body cylindrical, slightly reduced in 

 diameter at the tail. 



Setge strictly paired : aa = hc ; dd a little larger than half 

 the circumference of the body. 



Dorsal pores not seen. Clitellum not developed. Nephri- 

 dial pores from the third segment, on the anterior margin, in 

 the lines of the superior dorsal setse {d). 



At the intersegmental furrow x.-xi., a little laterally to the 

 lines of ventral bundles of setae, is present a pair of small 

 conical tubercles, contained in two small and not very deep 

 pouches ; these tubercles are in relation with the male pores, 

 but 1 have not been able to determine whether the pores are at 

 the summit or at the base of the tubercles (PI. XIII. fig. 1). 

 The tubercles correspond in shape with those drawn by 

 Michaelsen (12, pi. xiii. fig. 2) for Drawida sulcata, Mich. 



Female pores at anterior margin of the xii. segment, in the 

 lines of the superior ventral setae (b). 



Spermathecal pores at intersegmental furrow vii.-viii., a 

 little laterally to the lines of ventral bundles of setse. 



Internal anatomy. — Septa vi.-vii. — viii.-ix. somewhat 

 thickened. 



Four strong gizzards are distributed in segments xiii., xiv., 

 XV., and xvi. 



The paired hearts are found in segments vi.-ix. At 

 X. segment, close behind the anterior septum, a pair of trunks 

 originate from the dorsal vessel. These two trunks are 

 directed backw^ards in the ventral region, to unite with the 

 subneural blood-vessel close to the anterior surface of septum
