from the Seas of China and Japan. 143 
transversely handed with irregular red-brown lines and minutely 
spotted with pale yellow. The sole is also edged with pale 
yellow. At the caudal extremity of the foot there is a single 
conspicuous cylindrical terminal filament. I obtamed living 
specimens from 35 fathoms, off Tsu-saki, in Japan. 
Cancellaria Spengleriana, Desh. 
The latest account of the animal of Cancellaria I have seen 
is given by Dr. Gray in his ‘Guide to Mollusca.’ It is very 
vague and imperfect ; but the true position, I believe, is there 
suggested to be in close vicinity to Mitra. 
In Cancellaria Spengleriana the tentacles are broad, flat, tri- 
angularly subulate, wide apart, separated by the base of the 
retractile proboscis. The eyes are small and black, and are 
placed on slight tubercles at the outer bases of the tentacles. 
The mantle is furnished with a small siphonal fold. The foot is 
large, flat, truncate in front, with short side-angles, and acumi- 
nate and produced behind. Operculum none. 
The tentacles of this species are rendered dark nearly as far 
as the eyes by close-set small red-brown dots; the siphonal fold 
of the mantle is sparsely spotted with the same; both dorsum 
and sole of the foot are reticulate with red-brown lines, and 
dotted with the same colour. 
The animal is very shy, rarely showing more than the tips of 
the tentacles beyond the front edge of the shell. It has the 
power of considerably extending the fore part of the foot, using 
it as an exploring organ. 
Turcica instricta, Gould. 
I observed the animal of this shell at Satanomo-saki, where I 
dredged living specimens from a depth of 55 fathoms. It is the 
Trochus instrictus of Gould originally, then a Monodonta, after- 
wards (Otia Conchologica, p. 245) a Euchelus. It has, however, 
the tortuous columella and general characters of my genus Tur- 
cica, founded in 1854 upon a large species from Australian seas. 
My Monodonta angulifera, from the Philippines, is an allied but 
quite distinct species; and I have recently described a few 
others. These smaller Turcice with the outer lip sulcate have 
been separated by my brother and myself, in our ‘ Genera,’ as a 
subgenus of Euchelus, under the name of Perrinia. It would, 
however, have been more correct to have placed them under the 
genus Turcica. 
In this animal the head, neck, and upper part of the body 
are finely reticulate with light brown, and the tentacles and 
siphon are minutely speckled with opake white. The tentacles 
are long, white, and semipellucid ; the eyes are large and black,
