Drawida japonica (Mchlsn.) f. typica. 

 (PI. xvi, fig. I). 



Murree, N. Punjab; nit. 7000ft., ig-iv-1916. S. Gobind Sinoh. Numer- 

 ous specimens. 



External characters. — Length of a good average specimen 60 

 mm.; breadth 2 mm., or in the genital region ma}?^ be 2*7 mm. 

 Colour a greenish-grey, slightly darker dorsally. Segments 142. 



Setae closely paired ; aa is slightly less than be behind the 

 genital region, about equal to it in front; dd is equal to half the 

 circumference. The setae are very small on segment ii, if indeed 

 all of them are present ; they are large on the genital region. 



The nephridiopores may be present in three situations, — in 

 line with setae cd , or at the level of the ventral pair of setae, 

 or lastl}^ not far from the middorsal line; but there is no rule, 

 and no regular alternation. They are in all cases immediately 

 behind the intersegmental groove. 



The genital papillae, — a characteristic of the species, — are 

 variable in their situation, but seem to be always present in the 

 sexual animal. Each is an oval area slightly raised above the 

 general surface, with its long axis transverse, and with a circular 

 groove in its centre; the middle of each area is thus marked 

 off from the peripheral portion, and is perhaps a little, but not 

 much, raised above the level of the oval area in general. Fig. i 

 will give an idea of the appearance of the areas ; they are never in 

 the same position in two specimens; in number they may be two, 

 three or four; and they occur on segments vii, viii, ix, and xii. 

 They ma^^ be situated on either the anterior or the posterior part 

 of the segment, or more rarely at the middle of its length; they 

 may be either to the right or the left of the middle line, or seldom 

 midventral. 



With regard to the internal anatomy, it need only be stated 

 that there are two gizzards, in segments xii and xiii ; they are 

 annular thickenings of the gut-wall, separated by a thin-walled 

 section of the tube. 



Remarks. — This species is the most markedly peregrine mem- 

 ber of the genus; it has been found in Japan, China (f. siemsseni), 

 and the Bahamas (f. bahantensis,== Moniligaster hahamensis, Bed- 

 dard). The immature Drawida from Simla, said by Michaelsen 

 " probably, or rather doubtless" to belong to M. willsi (13), may 

 with at least equal likelihood be referred to the present species. 



Drawida hodgarti, sp. nov. 



(PI. xvi, fig. 2). 



W. 70/1. Rangamati, ChiUagong Hill Tracts, Bengal, ii-vii-1915. R. 

 Hodgart. Four specimens. 



External characters. — Length 113 mm. ; maximum diameter 

 375 mm. Colour a uniform grey, nonpigmented. Segments 164 ; no 

 secondary annulation. The rings of possibly sensory papillae found
