nherrans, sp. ii., e. (j. tlu^ occurrence of several sizes of aiifo- 

 zooids, the inluniin^' of almost tlie whole of a lar;^e tentacle 

 into the stonioihiMun, and the presence of ova and embryos in 

 the siphonozooid canals. 



The (linior|»hisni which Gray recorded in his Parncj ivrjia 

 nodosa is oontinn('(l in P. splendenSy sp. n. 



The cotnplc'x differentiation of the poly[)s in Agaricoides 

 A/cocki, Sinipson, is quite unique. The presence of numerous 

 Foraminifera in the stomodasum is also interesting. 



AmonjT^ other peculiarities we may mention the very 

 remarkable tentacles of Thesioide.t inennis, gen. et sp. n., the 

 remarkable base of AtdJioptiluin decipiens^ sp. n., the small 

 number of rays (3) in the pinnules of Fteroeidts triradiata. 



In regard to a collection which is a very feast of colour, we 

 may call special attention to the exquisite colour-schemes of 

 Pennotula veneris, P. pendida, P. spiendens, and P. indiai. 



Some of the epizoic animals are interesting, e. g. the 

 peculiar Solenogaster {R/iopalomeni'a gorgonophlla ?) on 

 Acaniptogorgia circium, sp. n.

Recently Messrs. S )werby and Fulton submitted to rae for 

 examination some shells they had received from Mr, Y. 

 Hi rase, of Kyoto. They were labelled Eulofa (^Ccelorus) 

 Cdviconus. and at first I was inclined to regard them as an 

 undescribed form, as upon comparison with that species they 

 presented several striking differences, having a more elevated 

 and convex spire, a smaller diameter, a more contracted 

 umbilicus, and a more laterally contracted aperture. U[)on 

 receiving" further material, however, several intermediate 

 forms were found, and the species, therefore, presents a con- 

 siderable amount of variation. 



The subgenus Coeforus, which, so far as our present 

 knowledge enables us to judge, appears to be restricted to 

 Japan, was established for the reception of the then oidy 

 known species — Eulota cavicollis — by Prof. Pilsbry (Proc. 

 Acad. Nat. Sc. Philad. 1899, p. 528). The gruup has not yet 

 been investigated anatomically; it wall, in all probability, 

 prove to be most nearly allied to Flectotropis, to which group, 

 in fact, the first species was originally assigned by the writer. 

 The presence in the two species, subsequently discovered, of
