JE. Manan-

cles about llie size and form of the dorsals, though capable of con- 

 traction into a blunt knob, and with a central opaque-white line. 

 Branchia3 slender, nearly linear, variable in length, disposed in six 

 or seven clusters on each side, each cluster having from two to six 

 rows of four papillae each, interior a bright vermilion color with an 

 opaque-white ring near tip. Foot narrow, transparent, the anterior 

 angles prolonged and generally folded transversely. Usual length, 

 one inch. 



Found by Dr. Stimpson at Grand Manan, on a gravelly bottom, 

 thirty-five fathoms ; by Rev. T. A. Swan, in tide pools at Kenne- 

 bunk, October. 



This common European species has at last been found 

 on our shores, and an examination of the lingual denti- 

 cles renders us quite certain of its specific identity. At 

 first sight it would not be distinguished from jE. diversa, 

 but a comparison of the tentacles and angles of the foot 

 gives most obvious differences. The description of JE. 

 Mananensis * scarcely differs in terms, as to quite vari- 

 able features. Dr. Loven intimates that this is D. branch- 

 ialis, Miiller.

Body elongated, a carmine line margined with silvery dots between the tenta- 

 cles and each tuft of branchiae, tail silvery ; tentacles subulate, simple, tipped with 

 silvery, branchite clavate, contracted at tip, which has two silvery zones, nucleus 

 pale chestnut, arranged in five or more distant groups of two transverse ranges. 



Body elongated, rather narrow and gradually tapering to a point, 

 arched above, of a pale drab color, margined above with light fawn 

 color ; along the back, beginning between the tentacles and between 

 each tuft of tentacles, is an elongated stripe of carmine, margined

Body pde white, tentacles rather thick ; 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 ; papillse slen<ler, 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 and a half inches.
