than in the typical species and their rows of spines much 
closer, and the latter character also distinguishes them 
from #. Normant. ‘The ventral bristles (Pl. III. fig. 12) 
approach those of the latter species more closely than those of 
Evarne Johnston?, being somewhat shorter than those of 
E. Normani, which, again, have stronger tips than those of 
LE. Johnstont. 
No scales are present. In all probability they approach 
those of £. Normant. 
By the lengthening of the tips of the ventral bristles and 
their general slenderness this species and 4. Johnstoni come 
near Antinoé and allied forms. 
3. On the British Species of Pholoé. 
To judge from the literature at present available, three 
species of Pholoé seem to be found in Britain, viz. P. minuta, 
Fabr., P. énornata, and P. eximia, G. Johnston. As indi- 
cated for many years, however, it would appear that the two 
latter merit only the position of varieties of the former. 
In the typical British example the head is somewhat 
rounded and bears a subulate median tentacle with a few 
papillz on its surface. Two (connate) eyes occur on each 
side, the anterior being the larger. Two short tentacular 
cirri, also with minute papillae on the surface, are placed 
laterally. Two prominent papilla project behind the eyes 
and sometimes overlap them. ‘The palpi are rather massive 
tapering organs with a smooth surface. The body is small, 
composed of 45 to 70 segments, and reaching about 2 inch in 
length as a maximum *. Posteriorly are two slender caudal 
styles. It is more tapering posteriorly than anteriorly in 
small specimens. ‘The dorsum is slightly convex, the ventral 
surface flattened, with a median groove in the preparations. 
In life the dorsum is of a pale pinkish colour, grained with 
brownish on some of the scales. A reddish mark occurs in 
front with a dark greyish patch behind. As Dr. Johnston 
observes, some are of a yellowish-brown colour, dusky along 
the sides. ‘The scales are ovate or reniform, with a series of 
cilia having moniliform tips along the outer border, and more 
sparsely along the posterior edge, while the tissue, especially 
at the inner region, is areolated. ‘The dorsal lobe of the foot 
forms a prominent process, with a convex margin externally 
for the dense tuft of bristles, which are slender, tapering, and 
spinous. Ventral lobe an oblique cone, with numerous 
* De Quatrefages mentions one of 68 segments and 45 pairs of scales.
