Head (PI. LXXXVIII, fig. 2) bluntly rounded and in the preparations devoid of eyes, 

 but with well-marked nuchal organs, which occasionally project as papillae on each side, 

 though in life they are almost foliate and richly ciliated (De Quatrefages). In some of 

 the preparations it is paler than the succeeding region, and shows a pigment-speck (eye) 

 on each side— in front of the brown band at the neck. Protrusible nuchal organs are 

 stated by Claparede to be present, and he mentions a median (over the brain) and two 

 lateral eyes, as, indeed, De Quatrefages 1 had long before described and figured. 



In general aspect this form resembles the Opheliidae in the iridescent skin, elongated 

 fusiform outline, the arrangement of the ventral longitudinal muscles which reach the
