OF NORTHUMBERLAND AND DURHAM. 115 
From the fishing-boats, Cullercoats; rare.—J. A. 
This is also nearly allied to H. papillosa, and requires further 
observation for its complete establishment.

Holis gracilis, Ald. and Hanc. in Ann. Nat. Hist. xiii. 
166. 
Among the rocks north of Cullercoats, rare—A.H. New- 
biggin—J. A. <A variety occurs, smaller, less slender, and with 
the branchiz of an orange colour: it may be distinct. We have 
also met withan Eolis, apparently belonging to this species, but 
with the branchie of a beautiful green colour. So great a vari- 
ation in colour is not usual in the genus. These varieties re- 
quire a re-examination, but the rarity of the species has hitherto 
prevented it.
