species G. dendyi, Spencer. The peripharyngeal aperture (in 

 spirit) is in about the middle of the ventral surface, some- 

 times a little anterior, and the genital aperture is situate at 

 about one-third of the distance from it to the posterior 

 extremity. The e3'es are arranged in a densely crowded 

 iriegular patch on each side of the head and continued in 

 single series all i-ound the horse-shoe-shaped anterior margin. 

 The ground colour ol the dorsal surface (in life) ranged from 

 pale indigo-blue to dark grey, blue-brown or almost black. 

 The mid-dorsal yellow stripe was sometimes so pale as to be 

 almost white, and frequently there was visible on each side 

 an ill-defined doi so-lateral band of a ligliter tint of the ground 

 colour, dividing each half of the dark dorsal surface into a 

 broader (more dorsal) and a narrower (more ventral) band. 

 The anterior extremity was pinkish, althouph sometimes the 

 pink colour was seaiceiy recognisable. The ventral surface 

 was bright blue, lighter in the middle line than elsewhere.

(Plate XI, Fig. 2.) 



This very handsome species was obtained by Professor 

 S[)encer in large numbers and would seem to be the common- 

 est species in the district visited by him. The body is long 

 and narrow, even when lying still and coiled into a knot ; 

 tapering a good deal more gradually in front than behind. 

 The shape of the dorsal surface vai-ies from more or less 

 flattened to strongly ridged, according to the position of the 

 animal ; it may be said to be cliaracteristically ridged, as 

 shown in the tigure. The worm reaches a very large size. 

 The largest specimen, aftei' pi'eservation in spirit, measured 

 1 15 mm. in length by G nnn. in greatest breadth; 1 could not 

 get it to crawl about actively so as to measure it when crawl- 

 ing. A smaller specimen, however, in which also a portion 

 of the posterior extremity was broken oft, measured about 

 1G8 nnn. in length b}' 5 mm. in breadth when crawling. 

 The peripharyngeal aperture (in s[)irit) is in about the 

 middle of the v^entral surface and the genital aperture about
