This species is known only by a drawing by van Hasselt, copied 
by Rang, and here reproduced. It may prove identical with the 
(prior) D. teremidi, but is larger, with more developed foliated ap- 
pendages on the body and fringing the border of the posterior disk. 
The following form described from the Sandwich Islands, is, per- 
haps, a variety : 
D. variegata Pease. 
Oblong, rugose, covered with small acute tubercles and more or 
less acute ridges; the tuberculations are scabrous and furnished, as 
well as the different portions of the body, with pale, soft cirrhi,. 
which are most conspicuous on the head. The posterior portion is 
obliquely truncated, from which part the body gradually tapers to 
the head; the surface of the truncation is convex, with the upper 
margin acutely elevated. The lobes of the mantle are closely 
appressed, the left overlapping the right, leaving two openings on 
the back, one a little in advance of the truncation, and the other on 
its center. Dorsal tentacles stout, deeply grooved laterally and 
somewhat swollen. Head convex above; oral tentacles short, stout, 
grooved laterally and much dilated outwards. Foot rugose, trun- 
cated in front, and acutely rounded behind, widest posteriorly. 
Color greenish-olive, variegated with brown, white and green ; inside 
of the lobes light brown dotted with white; a stripe of tawny brown 
along sides of the foot. Foot dark orange. Length 10 inches.

Quoy and Gaimard collected a form which they refer to this 
species as a variety, at Mauritius. This may or may not prove to 
be the same as the Java species, but the differences between the 
figures demand notice and comparison. For these purposes Quoy 
and Gaimard’s description here follows: 
Var. Pl. 28, tigs. 33, 34, 35, 36. 
Very large, conical, truncate ; roughened by fringes and tuber- 
cles; dirty dark green, variegated with brown and buff spots. M. 
Rang, in his beautiful monograph of the Aplvsias, has figured a 
species drawn by van Hasselt in Java, having much in common
