SPECIES DESCRIBED AS BRITISH, BUT WHICH I AM NOT ABLE 
TO APPORTION TO THEIR TRUE PLACE, FROM THE LACK 
OF PERSONAL ACQUAINTANCE WITH THEM. 
Alderi (Cocks). “ Body cylindrical, hyaline, smooth ; numerous grass- 
green longitudinal striae ; tentacles twelve, short, obtuse, with a continu- 
ation of the green line on the posterior sm’face of each. Disk and mouth 
crimson, the latter marked with eight spots of same colour, but much 
darker; edge of disk entire; suctorials minute, numerous, imbedded.” 
Deep water, off Falmouth. 
Pellucida (Cocks). “ Body cylindrical, smooth, opalescent ; numerous 
white longitudinal grooves ; suctorials minute ; tentacles short, filiform, 
transparent, plain ; mouth small ; disk circular, flat, crossed by opaque 
white lines ; edge entire.” Falmouth. 
Yarfellii (Cocks). “ Body conoid, hyaline, with twenty-four longitu- 
dinal semi-opaque white striae ; suctorials numerous, minute, imbedded. 
Three rows of tentacles, short, obtuse (rather clavate), spotted all over 
with white. The ovarian filaments, &c. distinctly seen through the trans- 
parent tunics.” Falmouth. 
Bella (Cocks). “ Body cylindrical, hyaline, spotted with yellow ; 
twelve longitudinal opaque white striae ; mouth bright orange-red ; two 
yellow patches extending from the angle on each side to the base of the 
tentacles ; tentacles twenty, long, filiform, dotted anteriorly, and tipped, 
with yellow.” Falmouth. 
Z/astota (Wright). “Base .adherent to rock; not exceeding column. Column 
smooth ; height about equal to breadth (one inch). Disk hollow, hardly 
equalling diameter of column. Tentacles numerous ; in five or si.x rows, 
set close to m.argin ; nearly equal ; very conical and short ; thickly 
crowded. Mouth set on a cone ; lip tumid, furrowed. Column and disk 
sienna-brown, or salmon colour. Tentacles light brown, with two white 
bars across the base, tip slightly white or translucent. Lips orange or 
brick-red.” Berehaven, Co. Cork. 
N.B. The above five species seem all referrible to that group of the 
genus Sagartia, which I have provisionally named TJwe. ' 
Intestinal^ (Fabric.). “ Body cylindrical, the upper half suddenly con- 
tracted and narrow.” — “ When contracted, the body seems like two broad 
rings, of nearly equal breadth, and about half an inch in diameter ; when 
expanded to nearly two inches, the body consists of two cylindrical por- 
tions of different dimensions, smooth, pellucid, yellowish ; a few longi- 
tudinal white streaks ; disk not expanded ; tentacles about eighteen, 
filiform, in two rows.” (Fleming.) Shetland.
