The following are descriptions of the various. species mentioned 
above :— 
CRUSTACEA. 
CoPEPODA-CALIGOIDA. 
Genus Pandarus, Leach (1816). 
In a previous paper* I gave a description and figures of Pandarus 
bicolor, Leach. These specimens had been obtained from the Tope, Galeus 
canis, Rondel. I have now to record the same kind of parasite from the 
Picked Dog-fish, Squalus acanthias, Linn. A considerable number of 
these fishes, captured off the West of Scotland and landed at the Fish 
Market at Aberdeen in March of this year (1908), were examined at the 
Laboratory at the Bay of Nigg. On these Dog-fishes quite a number 
of Pandarus licolor were observed; they resembled those previously 
described in form and colour. Figure 19, Plate III., represents one of the 
specimens. The cephalon is ornamented by deep chocolate-brown pigment, 
as shown in the drawing ; the middle plates are also coloured, but not so 
deeply. The body seen from above is elongated and somewhat eliptical 
in outline, but flat when seen from the side. Among the specimens of 
normal form and colour was one that differed from the others in both 
characters, but especially in colour. This specimen is represented by figure 
18 on the same plate. This form resembles in some respects a species 
described in 1888 by Lay under the name of Pandarus sinuatus, and to 
that species I was at first inclined to ascribe it. Probably, however, it
