Kroppen cm. (> Ctm. lang. Hovedet noget bredere 

 end langt, ender forti] i to afrundede Prominentser (Tab. I, 

 Fig. 11). Tentakelbasis meget lang, Tentakelen selv tynd. 

 omtrent 4 Gange Hovedets Længde, Antennerue halvt saa 

 lange som Tentakelen. Tentakelcirrerne af Tentakelens 

 Længde; disse ligesom Tentakelen og Antennerue tæt cilie- 

 rede. Palperne noget længere end Tentakelen, tykke, runde, 

 med 6 Rader smaa Papiller. 15 Par Elytrer, der dække 

 hele Ryggen. Skællene forsynede med en enkel lang, ko- 

 nisk, haard Knude ved den bagre Rand (Tab. I. Fig. 13) 

 og forresten besatte med t;etstaaende sniaa haarde Knuder, 

 der ere lyse, men mod den bagre Rand blive lidt større 

 og sorttarvede. Cilier langs ydre Rand ta>tstaaende. spar- 

 somme langs bagre Raud. Desuden paa alle Skæl tiere 

 Foraminiferer, der imponere som hvide, skinnende Knuder 

 (Tab. 1, Fig. 14). 



Fodkuuderne med to korte Lapper, Ventralcirren 

 rækker ikke ben til Spidsen al' Knudeu ( r rab. I. Fig. 12). 

 Borsterne at' vanlig Form. de dorsale kortere end de ven- 

 trale, der nedenfor den enkle krummede Spids ere grovere 

 tvertandede end hine (Tab. I,- Fig. 12. a).

Dyret har megen Lighed med Lænilla glabra, Mahn- 

 gren. Tentakelen mangler. Antennerue yderst korte. Pal- 

 perne temmelig lauge, ikke meget tykke og fuldstændigt 

 glatte, ogsaa under Mikroskopet. Tentakelcirrerne lidt kor- 

 tere end Palperne. sparsomt eilierede (Tab. III. Fig. 6). 

 I dens Basalstykke tindes ikke som hos Lænilla glabra to 

 Bolster, men derimod en Acicula (Tab. III, Fig. it). 



Skællene fuldstændigt glatte uden Spor at haarde 

 Knuder (Tab. III, Fig. 7); langs ydre Rand nogle faa og 

 tynde Cilier; enkelte ogsaa indover Fladen et Stykke (Tab. 

 III. Fig. 8). Fodknudernes (Tab. III, Fig. 10) dorsale 

 Gren forholdsvis temmelig stor og langt fremragende; Yen- 



mueli more coarsely dentate than the dorsal. tb,e latter 

 being minutely serrulate (Pl. I. hg. 10).

' Body about !>"" in length. Head somewhat broader 

 than long, terminating anteriorly in two rounded prominen- 

 ces (PI. I, tig. 11). Base of tentacle exceedingly long; 

 the tentacle itself slender, about 4 times the length of 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 antenme, closely ciliated. The palps, 

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

 row's of minute papilhe; 15 pairs of elytra', covering the 

 whole of the back. The 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 Foraminifera, having the apjjearauce 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 (PI. I. fig. 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 (PI. I. tig. 12, a).

This animal bears a close resemblance to Lænilla' 

 glabra, Malmgren. Tentacle wanting ; antennæ exceedingly 

 short. The palps comparatively long, not very thick, and 

 — even under a lens — quite smooth. The tentacular 

 cirri, sparingly ciliated, somewhat shorter than the palps 

 (PI. III. tig. 6). Their basal portion not furnished, as in 

 Lænilla glabra, with two bristles, but with one acicula 

 (PI. Ill,' tig. 9). 



The scales completely smooth, without a trace of hard 

 protuberances (PI. III. rig. 7); along the outer margin some 

 few delicate cilia, and also, a little inwards, on the surface 

 (PI. Ill, rig. 8). The dorsal branch of the pedal protube- 

 rances comparatively large, and much produced ; the ventral
