194 DREDGING REPORTS. 
Lagena distoma (P. and J.), a delicate, much elongated, one 
chambered species, having an aperture at each end and traversed 
by faint longitudinal strie. This has only recently been noticed 
as a British species from a single shell found in the sand dredged 
by Mr. Jeffreys in the Shetlands. Messrs. Parker and Jones 
state that it occurs on the Norwegian coast, a fact of interest in 
connection with Mr. Alder’s remarks on the boreal character of 
the Northumbrian marine fauna. Thus our list of the Lagenida 
is again complete, the whole of the species recorded as British 
being found on the Northumberland coast. 
In the sand from the second locality named, single specimens 
of two forms not obtained last year were found, viz. :—Cristellaria 
subarcuatula, Will. (C. crepidula, F’. and M.), and Rotalina ma- 
milla, Will. (Discorbina rosacea, D’Orb.), both valuable additions 
to our local fauna. 
A full-sized specimen of Cassidulina levigata (D’ Orb.) confirms 
its occurrence on our coast, noted last year on the strength of a 
very small and somewhat doubtful one. 
Report on the Alge, by George S. Brady. 
Dredging in deep water and on an exposed coast is not likely 
to be very productive in respect of Algz; nevertheless on this 
occasion some species were noticed which deserve record. Melo- 
besia calcarea, Ell. & Sol., was dredged in considerable abundance 
on rocky ground inside the Fern Islands. This species had not 
previously been taken in our district. In the same place occurred 
Phyllophora rubens, Grev., Gelidium corneum, Lamour. var. lati- 
folium, and a Callithamnion, probably C. Borreri, Ag., and if so 
a very desirable addition to our Flora. . Only one specimen was 
found, and that so small that we cannot pronounce certainly as 
to the species. In twenty-five fathoms, on a gravelly bottom, 
about six miles east of Holy Island, we brought up a splendid 
specimen of Desmarestia ligulata, measuring nearly eight feet in 
length. The plant was perfect even to the scutate root, and 
we suppose must have grown in the place where it was dredged,— 
certainly an unusual depth for marine vegetation of that character.
