LiTUARIA PHALLOIDES (Pallas). 



A single specimen of this, labelled " Dutch Bay, Ceylon," was 

 sent along with the Cavernularia just described. It presented no 

 features of special interest, and differed from other specimens 

 which have already passed through my hands (Marshall and 

 Fowler, " Pennatulida of the Mergui Archipelago," Joiirn. Linn. 

 Soc, Zool. xxi.) only in the point that the siphonozooids practically 

 filled all the space between the autozooids, instead of forming 

 rings round them. A plane of bilateral symmetry, mentioned in 

 the paper quoted, was also indicated here. The specimen, as so 

 often happens with Pennatulids, had been apparently truncated 

 above and scarred over ; a new autozooid and several siphonozooids 

 had been formed on the scar.

[Eeceived April 2, 1894.] 



The specimens of worms now described I owe to the kindness 

 of Mr. Alvan MiUson, Assistant Colonial Secretaiy at Lagos, 

 to whom I have frequently had to express my indebtedness 

 for material. Within the last few weeks I have received from him 

 a number of tubes containing a large number of specimens of 

 Earthworms, which proved to be referable to four species. Of 

 these I only describe three in the present communication ; the 

 fourth was not new, but was found to be a particularly hue speci- 

 men of my species SipJionoc/ aster millsoni ; this specimen I have 

 sent to the Oxford Museum. The remaining species belong to the 

 family Cryptodrilidge, which is not weU represented on the African 

 continent, so far as our present knowledge enables a judgment to 

 be formed. The most characteristic family of Earthworms of the 

 Ethiopian region are unquestionably the Eudrilidse, which are 

 indeed limited to that continent, with the sole exception of the 

 almost ubiquitous genus Eudrilus. So abundant are the members 

 of this family that it is really a remarkable fact to receive a 

 collection of Earthworms from that part of the world which does 

 not include representatives of that family. Such, however, is the 

 case with the collection upon which I report here. It may be 

 noted, however, that the Cryptodrilidse are rather more abundant in
