16. Rhynchodemus guttatus, n. sp, 



Undersurface much spotted irregularly with numerous small 

 blackish dots on a whitish ground. In the median line of the 

 dorsal surface is a very narrow jet black stripe bordered on either 

 side by a slightly wider but narrow white linear stripe sparingly 

 dotted here and there with minute black spots visible with a 

 lens ; external to each of these again is a broad band of shining 

 black, towards and at the extremities much broken up into 

 numberless small black spots and blotches ; beyond each of these 

 is a narrow lighter blotched band on the side of the body. The 

 margins of all the bands and stripes somewhat ragged : the white 

 stripes disappear near the extremities. 



Two specimens alive and extended 4 cm. and 2 cm. long respec- 

 tively, 2 mm. broad ; the former in spirit is 14-5 mm. long, 3 mm. 

 broad, the mouth 8 mui. behind the anterior extremity, the genital 

 orifice 3 mm. posterior to the mouth.

We have twice seen at Mt. Wilson what we believe to be a 

 specimen of this species, but on both occasions it disappeared 

 before it could be examined. Another specimen sent us by Mr. 

 Cox is damaged, and we are therefore doubtful about their 

 identity. The white stripes at once distniguish this species from 

 any of the others. 



17. Rhynchodemus trilineatus, n. sp. 

 (Plate V. figs. 11 and 12). 



Undersurface whitish flecked with black spots. The dorsal 

 surface with a broad shining dark purplish-brown almost black 

 band, which shows a median, and on each side a marginal, linear 

 longitudinal black stripe ; beyond which on each side a narrow 

 lighter band, the lines of demarcation formed by the marginal 

 stripes very conspicuous, and anteriorly at the level of the eyes. 

 Length crawling and extended 3 cm., broad 2 mm.
