little for abit three quarters of the length, when the sides converge and 
form posteriorly a somewhat wedge-shaped extremity. The anterior end 
is broadly rounded, inclining to angular in the middle, where the valves 
meet; greatest breadth equal to height; height about 4 the length. 
Surface of the valves smooth, but having a slightly resinigus appearance. 
Length, °35 mm. 
Habitat.—Off St Mouance, not very rare. Specimens of this form have 
been dredged on several occasions at this place, depth 12 to 14 fathoms, 
bottom clean gravel and sand. The animal has not yet been made out, 
the species is therefore for the present doubtfully referred to Cythere.

Habitat.—Brackish water pools by the shore at Aberlady Bay, common. | 
Associated with Cytherura gibba (Miiller), Candona candida (Miller), 
Trochamina inflata (Mont.), Haplophragmium canariense, &e., Granton 
Harbour (Robertson). I have this species also from Montrose Basin and 
from Orkney; it is a brakish-water species. The aboveare the only records — 
of its occurrence on the east of Scotland.

Habitat.—Near the mouth of the Estuary, moderately common. This 
species is new to the east of Scotland.

Habitat —Largo Bay, rare (dead), frequent in brackish-water pools at 
Aberlady Bay (living); Granton Harbour (Robertson) ; it occurs also in 
Montrose Basin. This is a brackish-water species, and is sometimes ob- — 
served in moderate abundance where the water is only slightly saline. Its 
occurrence in Largo Bay and in Granton Harbour is probably accidental.
