Tv:o New Species of Australian Land Leeches. 157 



The second, apart from external colour markings, diflFered only 

 from the latter in having seven and a half annuli between the 

 openings. These two are evidently more closely allied to one 

 another than either is to PhiUemon, and the three are sharply 

 marked off from other leeches by the presence of two jaws. 



There can be little doubt that the one with seven-and-a-half 

 annuli between the pores is identical with the one referred to the 

 genus Geobdella by Whitman, and for this I propose the name of 

 G. whifmani [Fig. 2.] 



The form with seven annuli between the pores is evidently 

 closely allied to, though distinct from this, and for it I propose 

 the name of G. australiensis [Fig. 1.] 



The descriptions of these are as follows : — 



^ Geobdella whitmani, n. sp. 



Total length in alcohol upwards of 40 nnn. The number of 

 annuli, including those represented at the anterior end by the 

 four oculiferous rings, is 95. The first complete annulus is the 

 5th, and the last complete the 92nd. 



Eyes, five pairs, first four in front of the first distinct annulus, 

 the fifth on the 7th annulus, and separated from the fourth by 

 two annuli. 



Nephridial pores open on the last annulus of the segment, the 

 first are in front of the fifth eye, and the last underneath a 

 prominent papilla as in Philjemon, in this case formed by the 

 93rd and 94th annuli. 



The male reproductive opening is between the 29th and 30th, 

 and the female in 37th annulus. 



Colour markings. Body warm rusty brown, dorsally there is 

 a more or less distinct light band edged by a dark line, and on 

 either side are patches of darker pigment. In each of these 

 is a light band and occasionally these lighter bands may be 

 continuous with one another, forming on either side a lateral 

 band which may run along the greater part of the length of the 

 body. The dorsal band does not usually extend along the 

 posterior sixth of the body, which is here mottled with dark 

 patches.
