JONESIELLA. A] 
Caudal segments very short and broad; sete finely 
aculeate. Jiength 33rd of an inch (1:1 mm.). 
This species occurred plentifully in a dredging made 
off Porcressa Bay, Scilly, in twenty fathoms, on a 
bottom of hard sand; also, less plentifully, in thirty- 
five fathoms off Red Cliff, Yorkshire.

This differs from the preceding species chiefly in 
the structure of the mandibular palp and the first and 
fifth feet. The basal joint of the mandible-palp is broad, 
and the two branches short and stout (Pl. XLVIII, 
fig. 15). The second joint of the inner branch of the 
second foot is twice as long as the first joint. The 
basal joint of the fifth foot (fig. 17) 1s somewhat 
rounded at the apex, and of moderate width ; not much 
broader than the outer joint. Length 39th of an inch 
(85 mm.). 
The following are the localities in which J. spinulosa 
has been noticed :—Westport Bay (Ireland), taken in 
the tow-net; dredged off Hartlepool on a sandy 
bottom; and in a depth of thirty-seven fathoms six- 
teen miles off Hawthorn (Durham), on a muddy bottom; 
in all cases sparingly. 
The resemblance between this and the preceding 
Species is, perhaps, too close to be altogether satis- 
factory, especially as specimens of the male of J.
