216 DE. W. C. m'iNTOSH on the PHYL10D0CID2E. 



riorly, with four pale terminal tentacles. In front of eacli eye is 

 a bright rose-red band slanting downward and backward, and then 

 turning round to join the larger I'ose-red area behind. Moreover 

 a pinkish band from the centre of the snout joins the latter 

 behind the eyes, which are thus encircled by a pale area. A 

 broad mass of rose-red occurs behind the eyes, the central part 

 being pale, while the lateral divisions assume a somewhat trian- 

 gular outline, as seen from the dorsum. The same rose-red hue 

 tints the bases of the tentacular cirri and passes some distance 

 along their columns. An ochre-yellow band proceeds from the 

 foregoing rose-red region backward aloug the median line of the 

 dorsum to the tip of the tail. Throughout the first three seg- 

 ments it is flecked with reddish grains, but thereafter the baud is 

 bright yellow. Each lateral region of the body is minutely flecked 

 with red, especially the anterior third ; and, further, the pigment 

 has a tendency to be arranged iu transverse bars or streaks. The 

 general tone of the rest of the body and lamellae is pale buff". 

 Besides the latter hue on the ventral surface, a rose-red band oc- 

 curs from the line of the first tentacular cirrus to that of the first 

 foot ; so that when the animal rests on the side of the glass, it 

 very closely resembles the abundant JSTemertean Amphiporus lac- 

 tijloreiis^ Johnst., with its reddish ganglia. 



There is nothing peculiar in the shape of the head, except that 

 it is hardly difi'erentiated in the living animal from the succeeding 

 segments, the whole presenting a somewhat elongated appearance, 

 while the tip of the snout is blunt. The eyes are circular and 

 comparatively small. The proboscis is withdrawn in the specimen. 



The body is somewhat broad in comparison with its length. 

 The superior lamellae are lanceolate, and are borne out from the 

 body on prominent pedicels. The bristle-bearing process is emar- 

 ginate ; and the bristles have rather slender shafts, with the usual 

 enlargement at the distal end, which is spinulose along the ter- 

 minal curves. The process at the tip is elongate and finely ser- 

 rated ; and the striae on its blade slope from the point and edge 

 downward and backward. The ventral lamellae are also lanceo- 

 late, but much more acutely pointed, and project beyond the tip 

 of the bristle-bearing processes. 



The characters of the species are well defined, the small size of 

 the eyes at first sight distinguishing it from the majority of its 

 allies described by Malmgren and Claparede
