tion. When the animal was well extended, the head was 

 flattened and lancet-shaped in outline, hut it was not well 

 marked off from the body. The secondary grooves, running 

 forward from the main cephalic grooves, were very distinct on 

 the dorsal sui'face and sides of the head, eight on each side ; on 

 the ventral surface they were less distinct. I know of no other 

 species of Carinella with secondary cephalic grooves. No 

 eye- spots were present. "With the exception of the colour- 

 less anterior portion of the head, the whole animal was of a 

 brilliant vermilion colour ; the ventral surface somewhat paler 

 than the dorsal. Along each side of the body ran a pale line 

 which on the head ciu'ved down on to the ventral surface to 

 meet its fellow in front of the mouth. Minute specks of opaque 

 white (? gland-cells) were scattered all over the surface of the 

 body. Length, 15 mm. ; width, 1 mm., or somewhat less when 

 well extended.
