Exterior aspect: The single specimen was very contracted, the central part of the pedal disc and a part of the actinopharynx di-sturU'd, so that the tilanients were conspicuous. In this stage the si)fciinen was cake-like. The j)edal disc is well developed and provided with a cuticle, the column smooth without distinct tubercles but with irregular furrows in part, between flattened thickenings, probably due to contraction. The distal, involved part is longi- tudinally furrowed. Possibly the margin is not ; owing to the strong contraction of the body it is difticult to decide the nature of the margin. As far I can see, the ridges of the uppermost part of the column enter into the outer tentacles without definite limit but there are no thickenings on the basal outer sides of the tentacles. The tentacles are short but broad, irregularly wrinkled, owing to the contraction together from the sides and not / ' y â .-.«'/ /:â â ym- â if there were only two cycles of tentacles. About the inner half of the oral disc is devoid of tentacles. The actinopharynx is of ordinarv length and jirovided with 2 siphonoplyphs. Anatomical description: Owing to the strong contraction of the s])ecimen and the bad j>reservation I cannot give a detailed <lescription of the anatomy. The ectoderm of the pedal is of ordinary thickness and |)ig- niented, ita cuticle strong. The is thin in with that of the column, but thicker than the ectoderm, and fibril-
