623 



young ones hatched out in 8 days after, the period of hatching is 

 probably just within that time. The second capsule was found 

 by Mr. Dove alread}' deposited, lying beside the adult, and 

 occupied a similar time in transit. The darker pigmentation of 

 the young individual from this capsule and its somewhat greater 

 length, together with the fact of the capsule having been already 

 laid when found, lead me to infer that it was some days older 

 than the others. 



The capsules of this species are about 4 mm. in diameter. 



GrEOPLANA LYRA, n.sp. 



(PL xli., fig. 2.) 



Colour of dorsal surface light yellow, with three sharply defined 

 lines of dark brown. Starting from anterior end the lines are of 

 equal width until just over the peripharyngeal opening, when 

 they become somewhat broader, the median one more so than the 

 others, and continue thus as far as the genital aperture, when 

 they again resume their original proportions. 



The group of lines is well in the centre of the body, having a 

 clear space between the lateral ones and the sides of about ^ of 

 the total width of the body, and somewhat resembling the 

 arrangement of the strings of a stringed musical instrument. 

 At both ends the lines merge into one another. The anterior tip 

 is coloui'ed brown. 



Ventral surface of a somewhat paler yellow than the dorsal, 

 without markings. 



Eyes as usual, in a single row round anterior tip and in a 

 straggling line with moderate grouping for some distance down 

 the sides. 



In a spirit specimen, which is 25 mm. long by 3£ mm. at widest 

 part, the peripharyngeal opening is 1 5 and the genital aperture is 

 20 mm. from anterior tip. The same example when crawling 

 had a length of about 40 mm. Another individual was 50 mm. 

 in length when crawling. In repose the body is drawn up to a 

 broad strap-shape.
