This had 16 long slender tentacles, often recurved against the column 

 when well expanded in confinement. The disk was often protruded in a conical 

 torm with the 8 small labial lobes prominent. The disk had 8 flake-white 

 radial stripes separated by narrower lines of purphsh brown. The tentacles had 

 a basal spot of red brown on each side and a basal squarish spot of flake-white; 

 towards the middle a crescent-shaped transverse spot of white and a smaller 

 white spotnear the tip. Capitulum bright salmon-colour with eight mesenterial 

 lines of white and a circle of purphsh brown spots near the bases of the tentacles. 

 Greatest length, 38 mm. This, in addition to the littoral localities, has been 

 dredged by us in various places, in the Bay of Fundy and Casco bay, in 10 to 

 64 fathoms; also in Portland, Maine, harbour in 9 fathoms, July 28, 1873, (speci- 

 men figured, PI. XXI, fig. 6).

Tentacles more than 16, varying from about 20 to 26, or more. Rudi- 

 mentary mesenteries near the disk vary in number and arrangement, according 

 to age, often more numerous than the tentacles, sometimes as many as 36. 

 Perfect mesenteries have a thick longitudinal muscle; all are fertile; two pairs 

 of directives; basal muscle well developed. 



Wall of column has imbedded capsules of nematocysts; scapus has its meso- 

 glcea thickened; its epidermal coating is firmly attached.

Column very elongated, cylindrical, with eight longitudinal sulcations, 

 between which it is somewhat swollen in the form of broad, rounded, slightly 

 prominent ridges, crossed in contraction by numerous strong transverse wrinkles. 

 The tentacles are about 24 to 36 in number, varying with the age, arranged 

 somewhat crowdedly in two rows close to the margin. They are long, slender, 

 tapering to a point, the outer ones a little shorter than the inner, whicli are 

 twice longer than the diameter of the disk, or even more; mouth with four 

 small prominent lobes on each side. 



The colour of the scapus coating is usually yellowish brown or mud-colour, 

 but varies according to the colour of the mud where found; the basal naked 

 area is pellucid yellowish white; capitulum yellowish white surrounded, about 

 midway between the tentacles and sheath, by a ring consisting of eight lunate, 

 arrow-shaped, or square, opaque white spots, which are close together and 

 sometimes extend downward at their lower angles, forming a white line along 

 the sides of each sulcation; sometimes there is a trace of another ring of smaller 

 white spots lower down; tentacles transparent yellowish white, sprinkled with
