tteir curve at the tip less marked. The minute nodes toward their distal region are also 
larger and more evident (PL IVa. fig. 11), while the tip is smooth. 
The semi pen n ate ventral bristles (PI. IVa. fig. 10), are distinguished from those of 
the previous species in being furnished with much more slender and elongated tips, but 
the terminal part or hook is shorter. The secondary processes or pinnae are more 
numerous, more slender, and more elongated. Moreover, throughout the lower two thirds 
it is observed that these show a shght enlargement toward the centre, so that the process 
is somewhat fusiform. Instead of the comparatively small number of these pinnae in the 
typical LcBtmonice producta, there are upwards of seventy in the present form. The 
basal hook is pro]3ortionally smaller, and it is often broken ; indeed the entire bristle is 
very easily injured, so that it is rare to have the pinnae perfect. Parasitic on the bristles 
were many beautiful thecate Infusoria with Diatoms in their interior, and stalked 
Acineta-ioxms, externally; and to one bristle a small Terehratida adhered. Foraminifera 
and Diatoms occurred in swarms on these organs. 
Only eighteen scales appear to be jDresent ; otherwise there is complete similarity 
between this form and the foregoing, in regard to both scales and cirri. The* number 
of the scales is, however, of comparatively little moment ; the main distinction lies in the 
structure of the dorsal spines and ventral bristles. It is an interesting feature also that 
the long lateral bristles of the cirriferous feet have a nodular surface towards the tip, 
and that the head dilfers in form as well as in the- absence of eyes. The papillae of the 
cuticle are ovoid. This appears to be a well marked variety of the foregoing. 
The example from 1950 fathoms had evidently fed on one of the Polynoidse allied to 
Evarne, and its intestinal canal contained shreds of skin, hosts of bristles, pieces of scales, 
numerous Radiolaria, and much granular debris.

Habitat. — The geographical range of this form is- considerable. It occurred in the 
trawl, along with a huge Balanoglossus from Station 147 (between Prince Edward Island 
and Kerguelen), December 30, 1873; lat. 46° 16' S.,, long. 48° 27' E. ; depth, 1600 
fathoms; bottom temperature 34°’2, surface temperature 41°‘0 ; Diatom ooze. Again in 
the trawl at Station 157 (midway between the Antarctic regions and Australia), March 3, 
1874; lat. 53° 55' S., long. 108° 35' E.; depth, 1950 fathoms; bottom temperature 32°T, 
surface temperature 37°'2 ; Diatom ooze. Along with it were a remarkable villous 
Trophonia, a rare Ascidian, and a Holothurian. It was also trawled at Station 241 (in 
the North Pacific), June 23, 1875; lat 35° 41' N., long. 157° 42' E. ; depth, 2300 
fathoms; bottom temperature 35°T, surface temperature 69°'2 ; red clay. Lastly at 
Station 244, June 28, 1875; lat. 35° 22' N., long. 169° 53' E. ; depth, 2900 fathoms;
