116 MARINE BIOLOGY OF THE SUDANESE RED SEA. 
penis terminates in a yellowish slightly bent stylet, exactly as in Bergh’s 
figures of Peronodoris cancellata. The spicules in the integuments are not 
branched, but sometimes bent and jointed. 
These specimens clearly belong to Peronodoris, and might be identified 
with P. cancellata but for the presence of a few denticles on the inner teeth. 
Also the branchial pocket is toothed. 
ASTERONOTUS HEMPRICHI, Khrenberg. 
(See Eliot, Proc. Zool. Soc. 1903, vol. i1. p. 384.) 
One very large specimen unaccompanied by notes. Hven in its preserved 
and bent condition it is 130 mm. long and 100 mm. broad. The general 
colour is olive-green but the larger warts are bluish. There is a distinct 
median ridge. The branchial pocket is closed by six very distinct teeth, but 
the whitish branchize can be seen through them at the bottom. There isa 
very broad and distinct chocolate band on the under side of the mantle. 
I doubt if the species of Asteronotus which have been described are more 
than varieties, and hemprichi certainly has priority as a specific name. The 
present specimen comes nearest to A. cespitosa (Van Hasselt), if that form is 
recognized as a valid species. 
ARTACHHA CLAVATA, Eliot. 
(Hliot, in Journ. of Conchology, 1907, p. 81.) 
One specimen. The notes merely say that it came from Engineer Island 
and was a “orey-brown dorid with warts and chocolate blotches under the 
mantle.” The internal characters and, in essential points, the external 
characters leave little doubt that it is A. clavata, but superficially it is not 
like the specimens previously found in Zanzibar and resembles rather Bergh’s 
figure of Phialodoris podotria (‘ Malacologische Untersuchungen,’ in Semper’s 
Reisen, Heft xvii. 1890, pl. 85. figs.5,6). The ground-colour is greyish white 
covered with low warts of a brighter white. The interstices between these 
warts bear mottlings and also dots of chocolate, and the whole dorsal surface 
displays a reticulate or stellate pattern formed by spicules radiating from 
the warts. This pattern is even clearer on the under side of the mantle. The 
rhinophores and branchize are both large and remarkably transparent and 
delicate. The labial armature, radula (20 x 50.0.50), and genitalia are as 
described for Artachwa clavata, |. c.
