and did not show, in any case, the distinctly, though minutely, 

 papillose surface of this species, which also appeared later and with 

 somewhat different habits. 



Elysia flava V., sp. nov, 



Plate IV. Figure 1. 



Body much elongated in extension ; head relatively small, hilobed 

 in front. Rhinophores rather small, about as long as the breadth of 

 the head, folded but not much expanded distally. Side flaps mod- 

 erately wide, undulated, rounded anteriorly, narrow posteriorly, and 

 extending nearly to tip of the pointed foot. 



Color of head, neck, rhinophores, back, and foot light yellow, with 

 white specks on the back, and faint dull brown markings back of 

 the head and on the sides of the neck. Outside of the flaps olive- 

 green, specked with white and covered with very minute papilla? ; 

 edges of flaps flake-white, with dendritic branches of white extend- 

 ing inward. Inner surface of flaps are almost black, due to the very 

 dark or blackish green, ai'borescently branched internal organs. 



Length, about 18 mm while living and in extension. 



Castle Harbor, at Waterloo, under stones at low-tide, April IV, 

 1901. Rare. 



Elysia picta V., sp. nov. 



Plate IV. Figure 2. 



A small, very brilliantly colored species. Body rather stout. 

 Head large and neck rather long ; rhinophores long, clavate, and 

 deeply folded ; their length is equal to twice the breadth of the head. 

 Side-flaps large and broad, their edges thin and strongly undu- 

 lated ; they extend posteriorly to the tip of the foot. 



Color of upper side of head, upper part of sides of neck, and 

 whole of back and inner surface of flaps dark reddish brown, with a 

 purplish spot between anterior ends of -flaps ; front of head bright 

 red; a line of the same red runs back on each side of the neck and 

 along the entire edge of the flaps to the end of the foot ; below 

 this red border there is a band of bright blue ; middle of head and 

 bases of rhinophores light yellow, and this color extends backward 

 as a broad median stripe on the neck, thus forming a cross-shaped 

 mark of yellow, which terminates posteriorly in a blue spot on the 

 neck, and in a blue band on each rhinophore ; on the latter the 

 blue is followed by a brown band, this by a wider red band, while 

 the tip is brown. A blue spot centered with yellow surrounds the 

 genital openings, on the right side of the neck.
