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. 

 (Pease). 



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. PI. 28, figs. 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 Aplysias, has figured a 

 species drawn by van Hasselt in Java, having much in common
