ENTOPROCTA. 



103. PEDICELLINA CERNUA (Pallas). Pedicellina echinata. 



Sars. 



On small seaweeds and corallines, near low-water mark ; fre- 

 quent. Alder, (a). 



Very common on all kinds of algae between tide marks, Culler- 

 coats. 



Dredged abundantly on hydroids and other Polyzoa from all 

 Stations, except VI. and IX., and from 40 fathoms east of Longstone. 



* var. BELGICA, Gosse. 



From Station V. 



104. PEDICELLINA BELGICA, Van Beneden. 



On other zoophytes, Cullercoats ; rare. Alder. 



Hincks does not include this in his list of British species, and 

 Alder gives neither description nor figure by which his identification 

 might be confirmed. 



105. ASCOPODARIA GRACILIS (M. Sars). 



On the under side of stones, and on the stems of zoophytes, 

 Cullercoats and Tynemouth. Alder. 



On shells, stones, hydroids and Polyzoa from Stations III., IV., 

 VII. and VIII. Very common. Also from 40 fathoms east of the 

 Longstone, 32 fathoms east by south of Cullercoats, and between 

 tide marks, Cullercoats. 



106.* LOXOSOMA NITSCHEI, Vigelius. 



In June of this year a species of Loxosoma was found growing 

 in one of the tanks of the aquarium here in very great abundance. 

 It is growing on several very different kinds of Algae, two or three 

 hydroids, several species of Polyzoa, including Alcyonidium hirsutum, 

 Cribrilina 'punctata, &c, and on a piece of coal. There are numerous 

 buds which move about independently, and expand and contract 

 their tentacles before being set free, and which swim about with the 

 head hindmost, and move in a series of somersaults after being 

 liberated. The chief differences between this species and L. singu- 

 lare, which of those described by Hincks it most resembles, are (1) 

 the peduncle is frequently longer than the body, (2) there are always 

 only eight tentacles, (3) the peduncle does not end in a foot. 



Dr. Harmer, of the British Museum, has kindly accepted 

 specimens for examination, and a further note on the species will 

 appear later.
