395 Part ITI.—HWighteenth Annual Report 
The antenne closely resemble those of Cylindropsyllus levis, but 
sae end joints are proportionally rather longer ; the secondary branches 
{protopodites) appear also to be slightly more elongated. The mandible- 
palp, which is moderately slender, is of greater length than the same 
appendage in Cylindropsyllus levis, and is composed of two joints, 
but the last joint is small (fig. 24). The maxille appear to be similar te 
those of the species named. The anterior foot-jaws (first maxillipedes) 
are small and apparently one-jointed; the single joint is somewhat 
dilated, and bears two elongate processes at the distal] end of the inner 
margin ; the terminal claw is also moderately large and stout (fig. 25). 
The posterior foot-jaws (second maxillipedes) are slender and two-jointed, 
aud armed with a moderately long, slender, almost setiform, terminal 
claw (fig. 26). All the thoracic feet -are as previously described. The 
caudal segments are nearly as long as the anal segment, and they are each 
furnished with a broad, sabre-like terminal spine nearly of the same 
length as the furcal segment, and each spine bears a secondary setiform 
process on the outer margin (fig. 29), The segments are also provided with 
one or two minute hairs. 
Description of the Male.—The antennules of the male are modified for 
grasping. The cephalo-thoracic and other appendages are similar to 
those of the female, except in the following particulars :—(1) The outer 
branches of the second pair of thoracic feet, which are moderately stout 
and elongate, are each armed with a stout elongated falciform terminal 
process, bent inwardly at uearly right angles to the joint from which it 
springs. These processes are somewhat similar to those on the outer 
branches of the second feet of the male of Cylindropsyllus levis, but the 
apex is somewhat differently modified, as shown by the drawing (fig. 30). 
(2) The short inner branches of the third pair differ from those of the 
female in having the first joint produced interiorly into a stout tapering 
spine, which is slightly sinuate, and extends beyond the end of the second 
joint ; the second joint is dilated—both margins being convex (fig. 31). 
(3) The caudal segments are provided with terminal spines that are stout 
and tapering (fig. 32). It may also be noted that the exterior spine with 
which each of the fifth feet in the female is armed is wanting in those of 
the male. 
Cylindropsyllus minor, though apparently not very common, is a widely 
distributed species ; it has been obtained not only off St. Monans, Firth 
of Forth, but also at Ballantrae Bank, Firth of Clyde. I have not, how- 
ever, observed male specimens other than those referred to in the pre- 
ceding description, which are from the Forth estuary ; probably the males 
are scarcer than the other sex.

In previous years I have recorded this curious species from the head of 
West Loch Tarbert (Cantyre), and from the Cromarty Firth, which 
hitherto appeared to be the only two Scottish localities where this 
copepod was known to occur. I have now to report two additional 
stations for Huntemannia, both of which are in the Clyde district. It 
was taken with the hand-net in shore-pools a little below high-water 
mark at the south-west corner of the Greater Cumbrae on May 6th, 1899, 
and in shore-pools at Inverkip on the 13th of the same month. At 
the latter place I obtained for the first time one or two females with 
ovisacs. I find that the females of this species carry two ovisacs oi 
average size, which contain a considerable number of small ova. What
