6 BULLETIN OF THE 
Holothuria Verrilli, n. sp. 
The following description applies to the specimen dredged at St. Vincent. 
The body is ovate. The tentacles, probably twenty, are drawn inside the 
body. The ambulacral appendages consist of small pedicels, scattered over 
the body ; they are rather distant on the greater part of the ventral middle 
line, and more closely packed along the lateral ventral ambulacra, and espe- 
cially on the posterior portion of the ventral surface. They are not arranged 
in rows. The integument is very rough from numerous crowded tables, 
which are of varying size, some being very solid and robust, others of a more 
delicate structure. The rounded or angular disks of the tables are always 
pierced with a large central hole, surrounded by a single or several crowns of 
peripheral holes. The spire is, as a rule, built up of four rods and one or two 
transverse beams, and terminates usually in four rather long teeth, each pro- 
vided with spines of considerable size ; the spire is rarely built up of more 
than four rods. The specimen is whitish. The interior structure does not 
present any differences from that usual in other species of this genus. 
The variations with regard to the tables appear to be considerable. In two 
of the specimens from Dominica, the spire often, but not always, terminates in 
four smooth teeth; in others, for instance those from Barbados and Grenada, 
the top of the spire hasa very irregular aspect, from numerous longer or shorter 
teeth, which are placed not only round the opening of the top itself, but also 
on a cross-like rod which covers this opening,

numerous specimens, which differ from those brought home by the “ Chal-

long spine. Lat. 39° 43’ N., Lon. 70° 55! 25” W. (1880); depth 1002 fathoms;
