been recently well described and figured by Dr. Brady,* 
from specimens dredged in Loch Fyne. 
Porcellidium viride, Phillipi. 
Found very sparingly. 
Zosime rubra, u. sp. (Pl. VIIL., figs. 1 to 8). 
Length 1-30th of an inch. Rostrum prominent ; short, 
thick, and pointed at apex, which bears two small 
hairs. Cephalothorax broadly ovate, broader towards base 
and apparently composed of one unsegmented carapaec. 
Anterior antenne (fig. 2) six jointed, broad at base, 
cradually narrowing towards apex. Posterior antennse 
(fig. 3) have the appearance of doubled arms, and appear 
to be six jointed (?). Mandible palp (fig. 4) on long stem 
and broadly toothed, basal portion undetermined. Maxilla 
not made out. First footjaw (fig. 5) short and wide, bearing 
several long spinous sete. Second footjaw (fig. 6) two 
jointed and terminated by a long and short spine. Second, 
third and fourth swimming feet (fig. 7) have outer and 
inner branch, each three jointed, the sete having long 
plumose hairs on each side and the spines bearing short 
hairs. Fifth feet of female rudimentary or wanting. 
Abdomen (fig. 8) four jointed, distinctly separated from 
cephalothorax, the two lower joints rather longer but 
narrower than the upper, and all are fringed with cilia. 
Caudal segments about twice as long as broad and termi- 
nated by two setw ; the outer one short and plumose; the 
inner very long and non-plumose. Colour, brilliant red. 
One specimen only, a female, of this beautiful little 
species was found, and it was partially covered and 
obscured by a parasitical alga. Its extreme minuteness 
made dissection very difficult, and some parts must remain
