26 MARINE INVERTEBRATA OF GRAND MANAN. 



third of the body bare. Foot broad, with short auricles in front. Mouth-disk 

 large, triangular. Colors : body pale whitish, dark in the middle line from the 

 viscera showing through ; papilla3 dark purplish, with the tips covered with intense 

 white specks. Length one inch. Found at Duck Island, under stones, at low 

 water. 



E. DiVERSA, Couth., Bost. Journ., ii. 187. The examples described by Couthouy 

 were undoubtedly mutilated, and I have heard it suggested that the species should 

 be exploded. At Grand Manan, however, I found specimens agreeing with his 

 description in the tentacles, color, etc., and prefer to catalogue them for the present 

 under this name. They occurred in 4 f. on Laminarice. 



E. Mananensis, St., n. s. Body pale white; tentacles rather thick; — the dorsal 

 ones brownish with pale tips, looking as if hollow, wrinkled ; — the oral blunt, curved, 

 with a row of opaque-white specks along the outer edge ; papilloa slender, irregular, 

 and variable in length, arranged in clusters along the sides of the back, of a bright 

 vermilion color, with a ring of opaque-white at the tips. Foot auricled, not very 

 broad. Length one inch and a half. It is narrower than E. sahnonacea, has 

 fewer papillae, and the dorsal tentacles are wrinkled instead of serrated. It was 

 taken in 35 f , on a gravelly bottom in the Hake Bay. 



DoTO CORONATA, Loven., Arch. Skand. Nat., 151. A pale brown variety, with 

 the papillaj dotted with white, was dredged on rocks in 15 f , near Duck Island. 



Dendronotus arborescens, a. et H., I. pi. iii. Fine large specimens are taken 

 at low water, and in all parts of the laminarian zone, on rocky bottoms. The most 

 common variety is white or colorless. The ova were deposited in August. 



Ancula sulphurea, St., n. s. This species approaches so near to A. cristata, 

 Loven, that perhaps the best mode of describing it will be to point out the diifer- 

 ences. It is much larger in size, being often an inch and a quarter in length ; and 

 proportionally broader. The mouth tentacles are longer; and the processes from 

 the dorsals arise at their bases, rather from the body than the tentacles. The 

 laminas also in the dorsal tentacles are more numerous. The number of branchial 

 tentaculiform ajipeudages varies from eight to twelve; they are of a light sulphur 

 color. The ova are deposited in a gelatinous belt, often three inches long, attached 

 by one edge in a serpentine manner to the rocks. It is very common under stones 

 at low water, and in the laminarian zone. 



Doris planulata, St., n. s., Fig. 14. Body broad, depressed; mantle expanded 

 widely beyond the foot, covered above with minute tubercles, and white with a row 

 of irregular bright yellow spots down each side just without the margin of the foot. 

 Dorsal tentacles elongated, slender; branchiae very small, consisting of about ten 

 delicate pinnated plumes. Foot narrow, truncated anteriorly, and extending pos- 

 teriorly to the edge of the mantle. Mouth very small, with a flat triangular lobe 

 on each side. Length 0.6 inch; breadth 0.45 inch. It differs but slightly from D. 

 Tcpanda, A. et H. 



Doris pallida, Ag., Bost. Proc, iii. 191 (no descr.). This species is remarkable 

 for the large size of the tubercles of the clpak. It is perhaps D. fusca, 0. Fabr., 

 F. G. 344 (non Miill.), and resembles much D. diaphana, A. et H. It was taken 

 in 25 f. gravel, off the northern point of Duck Island.
