O liter surface of lateral flaps olive-green below, becoming yellow- 

 ish above, and nearly white next to the blue submarginal band ; its 

 surface is thickly specked with yellowish white. 



Length, 16 mm ; length of rhinophores, 3.5 mm . 



Hungry Bay, April 5, 1901, under stones at low-tide ; two speci- 

 mens, pairing. (A. H. V.) Very rare. 



This species can be recognized at once by its many brilliant colors, 

 and especially by the marginal bands of red and blue, and by the 

 yellow cross on the head and neck. It can swim freely by means of 

 its large side-flaps. 



Elysia papillosa V., sp. nov. 



Plate IV. Figure 3. 



A small, grayish, distinctly papillose species. Body rather elon- 

 gated in extension ; head large ; neck long ; rhinophores large ; 

 strongly folded and wide at the tips. Side-flaps large, thin, usually 

 with the edges deeply undulated. Whole surface of body, head, 

 and outside of flaps thickly covered with small conical papillse. 



Color of head, neck, and outside of flaps grayish blue, paler ante- 

 riorly, and spotted with darker gray on the outside of the flaps, and 

 specked with flake-white over the whole surface. Inside of flaps 

 darker ash-gray ; the edges bordered with white. Rhinophores are 

 like the head, but with two indistinct transverse bands of orange- 

 brown on the posterior side. 



Length, about 12 mm in extension. 



Hungry Bay, under stones, at a very low-tide, April 5, 1901. 

 (A. H. V.) Rare. 



This species can swim freely by means of its ample lateral flaps. 



Lamellidoris aureopuncta V., sp. nov. 



Plate IV. Figure 9. 



A very small, nearly white species, with a row of small, round, 

 yellow spots near each lateral edge of the mantle. 

 . Body elliptical, obtuse at both ends. The foot is longer and 

 wider than the mantle ; anteriorly it is subtruncate with obtuse 

 angles, posteriorly it is rather obtuse and not much produced. The 

 mantle is evenly convex, nearly smooth, but hardened by spicules. 



Rhinophores small, slender, acute, with many oblique plications 

 and no distinct sheath. Gills or 7, simply pinnate, with fine 

 branches, retractile.
