drilus, and its vasa deferentia want at their distal extremity the 

 glandular bodies, present in this genus. By the absence of prostate- 

 glands Annadrilus agrees with Geoscolex and its allied genera. Rosa. 

 recently described an earthworm from Birmah, Bilimba papillata, which 

 has on each side of segment XVIII— XXIV a lateral ridge, like 

 that in Annadrilus; this species however is characterized by a 

 great number of copulatory papillae and the situation of its male pores 

 is unfortunately unknown. 



MONILIGASTRIDAE. 



This interesting family, distinguished from all other earthworms by 

 the absence of a clitellum (except M. sapphifinaoïdes Bourne ')), and by 

 the situation and the structure of their genital organs, is only repre- 

 sented by two small worms , one belonging to the genus Moniligaster , 

 the other probably referable to the genus Desmogaster. All the species 

 of this family, hitherto described, being found in the Indo-malayan 

 region (India, Ceylon, Luzon, Sumatra and Timor) it appears to be 

 specially characteristic for this part of the world. 



Moniligaster Perrier. 

 6. Moniligaster sp. 



Flores: Kotting, one specimen. 



A small worm, not measuring much over 18 mm. in length; the 

 number of its segments is about 100. Beginning with the sixtieth 

 the segments are probably regenerated, their longitudinal diameter 

 being smaller than that of the preceding ones, and their series of 

 dorsal setae not forming a continuous line with the dorsal series of 

 the anterior sixty segments. The body is cylindrical, tapering towards 

 the anal extremity. 



The cephalic lobe does not extend into the buccal segment , which 

 is very narrow. The distance between a dorsal and ventral couple of 

 setae measures two thirds of that between the ventral pairs. The 

 male pores are visible in the intersegmental groove X/XI 2 ), mid-

2) In my description of the gigantic M. Boutenii (Notes Leyden Museum IX, p. 97) 

 I staled the male pores to be situated between segment XI and XII; as it is now sett- 

 led that in all other Monilit/asier-species those pores lie between segment X and XI I 

 reexamined they specimens, for it might be possible that I made the error of one segment 

 in my enumeration, as was done by Beddard in his first description of Al. barwelli.
