21. Murex (Phyllonotus) acanthophorus, A. Ad. 
Proc. Zool. Soc. 1862, p. 272. 
Hab. Uakodadi, 5 fathoms. 
The dimensions of this species, which are not given by the 
author, are, length 43 mill., diam. 25; aperture oval, purplish 
within, 11 mill. long, 63 broad. Both the length and breadth 
of the shell will vary considerably according to the extent of 
the closed canal and the longitudinal varices ; but the size of 
the aperture is more constant. 
22. Murex (Cerastoma) endermonis, sp. nov. 
Testa ovata, spira turrita, fuscescens ; anfractus 6 superne decliviter 
tabulati, paululum supra medium angulati, infra angulum con- 
vexlusculi, varicibus 7 laciniatis superneque uncinatis instructi, 
liris spiralibus inequalibus scabrosis cincti ; regio umbilicalis valde 
perforata; apertura ovata, intus fusco-purpurea ; labrum varice 
ultimo fimbriato incrassatum, intus denticulatum, margine serra- 
tum, versus basim dente magno prominenti munitum ; columella 
ceeruleo-alba, medio fusco-purpureo maculata; canalis clausus, 
breviusculus, leviter recurvus. 
Long. 33 mill., diam. 14. 
Hab. Endermo Harbour, Yesso, 4 to 7 fathoms, sandy 
mud. 
Some of the spiral lirations, that at the angle of the whorls 
and three or four others in the last whorl, are much larger 
than the rest, and with the varices produce a coarsely cancel- 
lated aspect. The base of the prominent tooth is purple-brown, 
and the point white. 
Murex talienwhanensis, Crosse, and M. inornatus, Récluz, 
are allies of this species ; but both lack the labral tooth. 
It is only in young specimens that the varices are produced 
upward in a somewhat hooked manner; in the adult state the 
extremities are generally worn off.

Samarang, p. 38, pl. vi. f. 4, a, 0. 
Hab. Endermo Harbour, Yesso, 4 to 7 fathoms; bottom 
sandy mud. 
This species, which was founded upon a specimen in very 
bad condition now in the Museum collection, is allied to 
C. foliatum, Gmelin, from Sitka, Vancouver, and other loca- 
lities on the west coast of North America. 
The specimens dredged by Captain St. John at the above 
locality are in good condition.
