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 1H, of the hind body 12, and its wirfg 6 mill. Length of 

 the gill 7 mill.
