extent in Oikopleura longicauda as regards the whole of the nervous 

 system, the taste-organ, the tactile organs of the pharynx entrance, the 

 notochord, the oikoplast-epithelium, and the small groups at the spira- 

 cular opening. 



Ascidian Fixed in Skin of Holothurian.* — E. Chatton describes 

 what is probably " an cecological aberration " — the occurrence of a small 

 (undetermined) Ascidian fixed in the skin of Holothuria tubulosa at 

 Banvuls.

North Sea Cephalopods.t — E. S. Russell makes a preliminary report 

 on the Cephalopoda collected by the ' Goldseeker ' on the east and 

 north coasts of Scotland, round the Sketlands, and between the Shet- 

 lands and the Faeroes. The collection includes representatives of 

 sixteen species, of which three are new : Polypus faeroens-is (allied 

 somewhat closely to P. arcticus), Brachioteuthis bowman/ (very close 

 to the only other species of the genus B. beanii, and Taonidium pfefferi 

 (not unlike T. suhmi, and in some respects closely approaching Owenia 

 megalops). Examination of specimens from Naples and from Plymouth 

 has convinced the author that the common Moschites cirrosa Lamarck 

 of the British shores is identical with the Mediterranean M. aldrovandi. 

 The distinctly northern Rossia glcmcop-is Loven was got as far south as 

 Kinnaird Deeps ; about twenty specimens of Sepiola aurantiaca, hitherto 

 recorded only from Mediterranean waters, were taken at various locali- 

 ties on the east coast of Scotland, near Shetland, and in the Faeroe 

 Channel. Another new record is Galliteuthis reversa Verrill, which 

 has been found in deep water off the north-eastern coast of America 

 (Verrill), in Xew Zealand and Japanese waters (Hoyle), and in the 

 Mediterranean (Pfeffer). 



#. Gastropoda. 



New Pteropod from New England.} — C. H. Danforth describes 

 Psedoclione doliiformis g. et sp. n. The body is barrel-shaped ; the 

 head and posterior end are retractile ; there are three bands of cilia 

 like those of Pteropod larvae ; the head has one (anterior) pair of 

 tentacles ; the cephalocones are unarmed, three in number ; hood-sacks 

 are replaced by two thickened areas (ankistrophores) on the dorsal wall 

 of the pharyngeal cavity bearing a few (5 to 8) rather strong hooks ; 

 the radula has a broad non-cuspidate median tooth and five lateral teeth 

 on either side ; the foot is divided into three lobes ; the viscera fill up 

 the entire posterior part of the body. It may perhaps turn out to be a 

 paedogenetic larval form, but in any case it is new.
