the body and transversely truncate behind; the posterior free por-

front edge of the head-shield slightly excavated ; parapodia wide; 
the sole slightly longer than the body ; shell (figs. 17-20) internal, 
subconical, white, covered with a brownish epidermis ; pillar strong, 
reflected with a deep groove outside of it, the basal end projecting

Founded upon two individuals in the Copenhagen Museum. In 
color they agree almost completely. The dorsal shields are dirty 
light yellow marbled with black, marked with quite fine brownish 
lines (much finer than those of the ventral surface), and over this 
are strewn emerald-green dots, especially on the head-shield and 
most on its anterior margin. The margins in one individual shine 
through greenish-gray with whitish dots; in the other darker, quite 
blackish with yellowish dots. The wings or posterior lobes of the 
hinder shield are marbled gray and black, with numerous whitish 
dots and little spots, especially on the posterior side. The marginal 
part, especially above, grayish-green, finely white-dotted or darker. 
The sides of the body and the inner surface of the parapodial wings 
are brownish-gray or darker, dotted with yellowish. Gill yellowish. 
The sole as well as the outer surface of the parapodial lobes of 
alternate narrow, light dirty yellowish and brown longitudinal lines, 
the latter in large part showing rows of small spots or still finer 
lines of a yellowish color. The edge of the parapodial wings, es- 
pecially on the inside, are greenish-gray, punctate with whitish, or 
quite blackish, punctate with yellowish. The largest individual 
(from Guadeloupe) measures, length nearly 28 mill. (to posterior 
edge of posterior lobes) breadth 12, alt. 10 mill.; length of head 
shield 113, of the hind body 123, and its wing 6 mill. Length of 
the gill 7 mill.
