described, are so characteristic and striking that there can be no 

 doubt of its specific identity with our specimens. 



The body, in life, is usually yellowish olive-green, but it varies 

 from light yellowish green to dark olive-green ; both surfaces of the 

 flaps and the sides of the body are finely specked with black and 

 flake-white dots, often appearing to be slightly raised above the sur- 

 face. The side flaps are wide with thin flexible and usually undu- 

 lated margins, which are elegantly bordered with a narrow bright 

 orange band, outside of which the edge is marked by a black line. 

 The folded rhinophores are large and long, with the posterior side 

 orange and the edge black. There is often a white patch on the 

 top of the head. Under side of foot paler green than the body. 



This interesting species was found pairing and spawning in con- 

 siderable numbers on the shore of Castle Harbor in March, by A. 

 H. Verrill. It occurred mostly on a curious bright green alga 

 ( Caulerpa clavifera), on which it laid its eggs in a long coiled ribbon. 

 According to the notes, the egg-band, when first laid, floated freely 

 in the water, being attached only by the proximal end, but it was 

 afterwards cleverly coiled up and attached for its whole length by 

 the parent, before being left to its fate. The species became com- 

 paratively rare in a few days, perhaps retiring into deeper water. 

 Only a very few could be found at the same place after my arrival 

 in April. The last specimens seen occurred April 17th. 



Elysia subornata V., sp. uov. 



Plate IV. Figure 4. 



Head large ; body elongated, acute behind ; neck long in exten- 

 sion. Rhinophores large and long, folded and strongly expanded 

 at the tip. Side flaps large, pointed posteriorly : their outer sur- 

 faces and the sides of the body are covered with small scattered 

 verrucas. 



Color of body and outside of flaps olive-green, finely mottled with 

 grayish white. Close to the edge there is a very narrow orange- 

 brown line ; the extreme edge is darker brown. Inner surface of 

 flaps dark green with pale dendritic and inosculating vessels. Rhin- 

 ophores marked distally with brown ; more proximally there is a 

 gray patch ; base green specked with gray. 



Length, up to 25 mm in extension.

This species is evidently closeh' allied to E. ornata, but the latter 

 was very constant in its markings, in over 200 specimens examined,
