capitulum there are ten stripes of dull brown, alternately lighter and darker 

 corresponding with the tentacle bases; these stripes are specked with fla" 

 white irregular spots, becoming more evident near the tentacle bases. 



The tentacles have a pair of lateral brown spots on their outer bases, form 

 ing a conspicuous circle of 20 brown spots; their tips are translucent; on the 

 inner surface there are about 5 wavy brown bands and spots, some of them 

 extending around back of the tentacles; they alternate with transverse lines 

 of yellow or white; the basal band is the darkest and often V-shaped or 

 M-shaped. 



The mouth has 10 brownish labial lobes; the disk is pale yellow, with 10 

 radial rows of pale brown spots, running to the tentacles, separated by pale or 

 white mesenterial lines. Length about 1 inch (25mm); diameter of column 

 about 3 mm. Described from living specimens. 



Type locality, off No Man's Land, in 19 fathoms, Sept. 2nd, 1871, U. S. 

 Fish Commission. 



Halcampa (?) anomala. New form. 

 Plate XXXI; Fig. 4. 



This form, which must be abnormal, is remarkable for having an unusual 

 number and arrangement of the tentacles. 



It has 14 normal shaped tentacles, about equal in length, and 3 smaller 

 ones, each united to one of the larger ones as if it were partially split off from 

 it, or had arisen as a bud from its side. One of the larger tentacles stands 

 nearer the mouth than the others. The larger tentacles are thick, mostly 

 obtuse, rather longer than half the diameter of the disk as seen in the living 

 specimen, and probably not fully expanded. They are crossed by about 7 

 more or less curved or waved reddish brown markings or bands, alternating 

 with bands of yellowish white. 



The disk is ornamented with circles of reddish brown spots alternating 

 with those of yellowish white. Two lateral white spots at the base of each ten- 

 tacle run down on the capitulum. Column is pale flesh-colour. Length, in 

 expansion, 44 mm; diameter about 6 mm. Internal structure was not examined. 

 On account of its similar colouration it is referred with doubt to this genus, 

 though it has an abnormal number of tentacles. Described from a living 

 specimen. 



A single specimen was taken in Massachusetts bay, off Race point; Station 

 292, 19 fathoms, fine sand and mud, by the U. S. Fish Comm. in 1879. 



The branched form of some of the tentacles is doubtless abnormal.
