2 Prof. M'lntosh's Notes from the 



occurred in a tow-net at 111 fathoms off the West Coast 

 of Ireland (Southej'n). Another addition is hfoliplenes matpifi, 

 Southern, froui tlie same region, a pelagic form in wliieh 

 the hi>ad is rounded in front ; dorsal tentacles as long as the 

 head is wide, and slightly larger than the ventral pair, whieli 

 are placed far back, just in front of the mouth. At the 

 base of the head dorsally is a wide collar, projecting laterally, 

 and continued on the ventral side behind the moutli. No 

 eyes. Body 3*0 mm. long; segments thirty-five; width 

 across the feet 1 mm. Colour in spirit pale yellowish brown. 

 Foot with the pointed setigerous lobe projecting beyond the 

 cirri and the tip of the spine is just visible. The dorsal 

 cirrus is pear-shaped, the ventral bluntly conical. Bristles 

 with slightly curved shafts and a prominent process at the 

 tip. The terminal piece is long and slender, two to three 

 times as long as the free portion of the shaft (Southern). 



A third pelagic type is Lopadorhynchus uppendiculatus, 

 Southern, procured off the West Coast of Ireland in the 

 tow-net over 450 fathoms. The dorsal tentacles on the head 

 are twice as long as the ventral, which are not seen from the 

 dorsum. The ventral tentacular cirri are somewhat longer 

 than the dorsal, and on the basal piece of the ventral is a 

 rudiment of the third pair. Body 13 mm. long and 5 mm. 

 wide, narrowed posteiiorly ; segments twenty-three, of which 

 twenty-two are setigerous. Dorsally each segment is marked 

 by a transverse ridge running along the middle, so as to 

 have lozenge-shaped depressions in each intersegmental 

 area, and ridges also occur ventrally. Feet anteriorly 

 modified, but the typical foot occurs at the seventh, which 

 has a pointed setigerous lobe with a spine and a rounded 

 setigerous lamella with seventy-six compound bristles. The 

 dorsal cirrus is conical and larger than the ventral, the tips 

 of both being within that of the setigerous lobe. The 

 ventral cirrus has a filiform process at the tip and tlie 

 aperture of a multicellular gland near its base. Small 

 granules of dark purple pigment occur on the inner sides of 

 the cirri. 



The same form was described by Prof. Fauvel as 

 L. uncinatus a few years later, and he emphasized the 

 presence of the hooked bristles in the first two feet by his 

 title to the species.
