Body about 6'*" in leiigth. Head somewhat broader 

 than long, terminating anteriorly in two rounded prominen- 

 ces (PL I, lig. 41), Base .of tentacle exceedingly long; 

 the tentacle itself slender, about 4 times the length oi' the 

 head; the antenna; half as long as the tentacle. The ten- 

 tacular cirri of the same length as the tentacle, and both, 

 together with the antennæ, closely ciliated. The palps, 

 somewhat longer than the tentacle, thick, round, with 6 

 rows of minute papilhe; 15 pairs of elytræ, covering the 

 whole of the back. Tlie scales with a long, simple, coni- 

 cal, hard protuberance on the posterior margin (PI. I, ' fig. 

 13), and studded besides with small, closely set nodules, 

 light in colour, but changing to black and somewhat 

 larger towards the posterior margin. The outer and the 

 posterior margin furnished with • cilia, the former densely, 

 the latter sparingly. Moreover, on all the scales occur 

 divers P'oraminifera, having the appearance of white, lust- 

 rous granules (PL I.' tig. 14). 



The pedal protuberances with two short lobes; the 

 ventral cirrus not reaching to the summit of the protuber- 

 ance (PL I, tig. 12). The bristles normal in form, the dor- 

 sal . shorter than the ventral, which, a little below the 

 simple arcuate point, are much more coarsely transverse- 

 serrate than the former (PL I. tig. 12. a).

This animal bears a close resemblance to Lænilla 

 glabra, Malmgren. Tentacle wanting; antennæ exceedingly 

 short. The pal])s comparatively long, not very thick, and 

 — even under a lens — quite smooth. The teutaculjir 

 cirri, sparingly ciliated, somewhat shorter than the palps 

 (PL HI, tig, 6). Their basal portion not fui-nished, as in 

 Lænilla glabra, with two bristles. ' but with one acicula 

 (PL m.'tig, 9), 



The scales completely smooth, without a trace of hard 

 protuberances (PL lU, tig. 7); along the outer -margin some 

 few delicate cilia, and also, a little inwards, on the siu'face 

 (PL in, tig. 8). The dorsal branch of the pedal protube- 

 rances comparatively large, and much produced : the ventral
