have lost the red tint, and are fulvous. More or less of the under- 

 surface in all the specimens is concave in the median line, but this 

 may perhaps be due to contraction, though we have not noticed a 

 similar effect in other species. 



We do not think this can be Moseley's G. sanguinea, as it cannot 

 be said to closely resemble G. ccerulea, the body being more 

 depressed, and the oral aperture further back than in that species. 



Genus RHYNCHODEMUS. 



Rhynchodemus, Leidy, Proc. Acad. Nat. Sc. Philad. v, 1851. 

 " Corpus elongatum, sub-depressutu, antrorsum attenuatum, 

 utrinque obtusum. Ocelli duo subterminales." 



13. Rhynchodemus Moseleyi, n. sp. 



(Plate V. figs. 9 and 10). 



Undersurface whitish. Entire upper surface dark olive-green 

 almost black. A very narrow mesial dorsal black line bounded on 

 either side by a much wider stripe of ground colour ; external to 

 each of these stripes a black line slightly broader than the median 

 one, beyond which again the ground colour extends to the lateral 

 margin of the body. The ground colour is so dark that that the 

 longitudinal lines are difficult to detect. 



Length living 3* 3 cm. long, 3 mm. broad.

14. Rhynchodemus Coxii, n. sp. 



Above shining black with two narrow longitudinal azure- 

 blue lines enclosing a very narrow median longitudinal stripe of 

 the ground colour ; viewed with a lens the ground colour is seen 

 to be dotted with minute azure-blue specks, while the azure lines 

 have their margins ill-defined and somewhat irregular, and appear 

 as if dotted with black ; the lines continue right to the posterior 

 exti-emity, but begin some little way behind the anterior one 

 which is not coloured reddish. In spirit the lines become white.
