longest diameter, and is of a blackish colour ; it is therefore easily over- 
looked. The species have only hitherto been observed in Cromarty Firth, 
where it is not uncommon. I now record it for Loch Fyne, some 
specimeus having been obtained in a gathering of dredged material 
collected near Otter Spit, Upper Loch Fyne, on January 12th, 1899, 
Jonesiella fusiformis (Brady and Robertson).

This seems to be the most frequent representative of the genus in Loch 
Fyne; in the Firth of Forth it is Jonesiella spinulosa., B. and R., that 
is the more frequent species. Jonesiella fustformis occurs not rarely in 
material dredged on Tarbert Bank, Lower Loch Fyne ; it is collected here 
in almost every dredging that is taken. The latest record I have of 
Jonesiella fusiformis from this locality is December 12th, 1899.

This distinct but apparently rare copepod was dredged off Arisaig, 
Argyleshire, in 1892, though not described till 1895. No further 
specimens were observed till the present year (1899), when the species was 
again found; this time in some material dredged in the “Fluke Hole,” 
oft St. Monans, Firth of Forth, in 1896, and the examination of which 
had been delayed for want of time. ‘This species is readily distinguished 
from others of the same genus by the form of the secondary branches of 
the fifth pair of thoracic feet, which terminate in hook-like processes. 
The occurrence of the species in the Firth of Forth tends to indicate that, 
though it seems to be rare, it may at the same time be widely distributed. 
Canthocamptus tnconspicuus, sp. n. (Pl. XIV., figs. 1-8.) 
Description of the Female.—In general appearance this species is 
somewhat similar to Canthocumptus parvus, 'I’. and A. Scott. The length 
of the specimen figured measures from the foreliead to the end of the 
caudal furca 54mm. (about #4. of an inch). The antennules, as in the 
species mentioned, are short and six-jointed ; the third joint is longer than 
any of the others, being about equal to the entire length of the two 
joints preceding as well as of the two that follow it. The formula shows 
approximately the proportional lengths of the different joints—

The antenne are each furnished with a one-jointed secondary branch. 
The mandibles are small, and they are provided with a small one-branched 
but moderately elongated palp (fig. 3). The first pair of thoracic feet 
have both branches three-jointed ; the inner branches are considerably 
longer than the outer, and the first joint exceeds in length that of the 
second and third combined, as shown in the figure (fig. 5). The inner 
branches of the second, third, and fourth pairs, which are shorter than the 
outer branches, are only two-joimted, but the outer branches are three- 
jointed, moderately elongated, and sparingly setiferous (fig.6). The fifth 
pair are small and foliaceous; the basal joint is broadly sub-triangular, 
while the secondary one is small and ovate ; both are provided with a few 
sete, arranged as shown in the drawing (fig. 7). The caudal segments 
are slender and about as long as the anal segment (fig. 8). The female 
carries one ovisac.
