SAGARTIADiE. 
Tentacles. 
TENTACLE 
OF 
S. MINI AT A 
{front). 
Pellucid pale-brown, or yellowish, indistinctly annulated with 
dusky. The fi-ont face of each (except the outer row) is 
mai’ked with two longitudinal dusky lines, pai’allel with 
the sides, and meeting at the summit : these are some- 
times interrupted by a pale band crossing the middle of 
the tentacle. Below them, at the tentacle-foot, is a large 
space of white, -which is crossed by two bars of black; 
the upper one thick and very constant, the lower slender, 
and sometimes thinned away to a mere shade in the middle. 
Groups of tentacles often occur of a more or less opaque 
white, but barred like the others, -with which they form 
alternate clusters. Those of the outer row consist each of 
a pellucid sheath investing a core of scarlet or brilliant 
orange, resembling in appearance the central gland in the 
papilla of an Eolis. This effect seems to depend on the pig- 
ment being spread over the interior surface of the wall 
of the tentacle, which is unusually thick and colourless. 
Mouth. Orange-red. 
Size. 
Specimens attain a height of two inches, -with an equal 
width of disk. 
Locality. 
The south and west coasts of England, from Deal to Arran. Rock-pools 
and deep water. 
Varieties. 
a. Ornata. To the state above described, which may be considered as 
the normal colouring, I appropriate this name, which was applied by my 
friend Dr. T. Strethill Wright, to the species, which he described, 
believing it to be new. (Plate ii. fig. 4.)* 
Venustoides. Disk rich orange. Tentacles opaque yello-wish-white or 
pure white, marked, however, -with the two charactei’istic black bars ; the 
outer I’ow showing traces, more or less conspicuous, of the orange lining. 
This variety, from Ilfracombe and Torquay, has much 2>ri7na-facie re- 
semblance to S. venusta; but the specific marks of the tentacles, the strong 
crenation of the mouth, and the well-defined and concentrically striate 
i’adii are good signs of distinction. (Plate ii. fig. 3.) 
* IMy friend Mr. F. H. West has received a specimen from the vicinity 
of Boulogne, with the disk more variegated than is usual Avith our specimens, 
and which had this peculiarity, that one-half of the disk was flushed with a 
delicate rose-pink, and the opposite half with an equally lovely shade 
of green.
