Bemserkninger. Denne nyc Art kjendes ved sit over- 
ordentlig spinkle Legeme, do jevnt afinndede Iste ParEpi- 
merer, den fuldstsendige Mangel af 0ine og den line acre 
Form af Hofteleddet paa de 3 bagersto Fodpar. Da det 
af mig forst anvondte Artsnavn, tenella, alleredo er anvendt 
for on araerikansk Art, har jeg foretaget ovenstaaende For- 
andring med sanime. 
Beskrivelse. Legemet er (se PI. XIV, Fig. 7) saer- 
deles spinkelt, nmsten af cylindrisk Form, med Eyggen jevnt 
hvmlvet, nden Fortsatser eller T tender. 
Hovedet er forholdsvis stort, omtrent af sanime Lamgde 
som de 2 forreste Segmenter tilsammen, og har Sidehjor- 
nerne meget korte og stumpt tilrundede. 
Epimererne er sserdeles smaa, lavere end solve Kroppen 
og aftager successivt noget i Stprrelse bagtil. Iste Par, 
som er det storste, er noget skraat fortilrettet og smalt 
tilrundet i Enden. 
De 3 forreste Bagkropssegmenters Sideplader er kun 
lidet udviklede og bagtil nsesten retvinklede. 4de Segment 
er noget dybere end de foregaaende. 
Af 0ine Andes intetsomhelst Spor. 
Iste Par Folere or temmelig stmrkt forkengede, men 
dog kortere end Legemet, og meget tynde. Skaftets 2 
forste Led er omtrent indbyrdes af ens Lamgde og mere 
end 3 Gauge saa lange som 3die Led. Svoben er kortere 
end Skaftet og sammensat af 16 Led. Bisvoben er noget 
lsengere end Skaftets sidste Led og 4-leddet. 
2det Par Folere er 1 / 3 kortere end Iste Par og har 
Skaftets nsestsidste Led storst. Svoben er 8-leddet og kor- 
tere end Skaftet. 
Mnndregionen er nedentil stserkt fremspringende og 
saagodtsom fuldstamdig ubedmkket til Siderne. 
De 2 forreste Fodpar er som hos Slsegtens ovrige 
Arter meget ulige udviklede og temmelig rigeligt borstebe- 
satte. Iste Par er forholdsvis svagt bygget, med Haanden 
meget liden, neppe storre end det foregaaende Led. 2det 
Par er derimod sserdeles kraftigt, med den ydre Del stserkt 
fortykket og sammentrykt fra Siderne. Haanden er meget 
stor, nsesten firkantet, nden Torner, men i begge Kanter 
tset borstebesat. Endekloen er forholdsvis kort. 
De folgende Fodpar er sserdeles spinkle og kun spar- 
somt borstebesatte. De 3 bagerste Par er noget lsengere 
end de 2 foregaaende og udmserkede ved den smale, nsesten 
linesere Form af Hofteleddet. 
Halefodderne er alle omtrent af ens Udseende, med 
smalt lancetformige Grene. Sidste Par er neppe lsengere 
end det foregaaende, men har Grenene noget storre i For- 
hold til Stammen. 
Remarks. — This new species is distinguished by if s 
remarkably slender body, the evenly rounded 1st pair of 
epimera, the total absence of eyes, and the linear form of 
the basal joint of the 3 posterior pairs of legs. The Specific 
name T first selected, viz. tenella, having, as I found, al- 
ready been adopted for an American species, I saw fit to 
modify my appellation to that given above. 
Description. — The body (see PI. XIV, fig. 7) is 
exceedingly slender, almost cylindric in form, with the back 
uniformly arched and exhibiting neither projections nor 
teeth. 
The head is comparatively large, about the same 
length as that of the 2 anterior segments taken together, 
and has the lateral corners very short and obtusely rounded. 
The epimera are exceedingly small, less in height 
than the body, and diminish, backwards, successively some- 
what in size. The first pair — which are the largest — 
directed somewhat obliquely forward and narrowly rounded 
at the extremity. 
Tin 1 3 lateral plates of the abdominal segments are 
but slightly developed, and posteriorly almost rectangular. 
The 4th segment is somewhat deeper than those preced- 
ing it. 
Of eyes no trace whatever. 
The 1st pair of antennae are considerably elongated, 
shorter however than the body, and very slender. The 
2 first joints of the peduncle are about equal in length, 
and more than 3 times as long as the 3rd joint. The 
flagellum is shorter than the peduncle, and composed of 
16 articulations. The secondary flagellum is somewhat 
longer than the 1st joint of the peduncle, and quadri- 
articulate. 
The 2nd pair of antennae are one-third shorter than 
the 1st, and have the penultimate articulation largest. The 
flagellum is eight-jointed, and shorter than the peduncle. 
Tile buccal area juts forward considerably below, and 
is well-nigh entirely uncovered at the sides. 
The 2 anterior pairs of legs, as in all other species 
of the genus, are most unequally developed, and rather 
profusely furnished with bristles. The 1st pair are com- 
paratively feeble in structure, with the hand very small, 
scarcely at all larger than the preceding joint. The 2nd 
pair, on the contrary, are remarkably powerful, having the 
outer portion greatly inerassated, and compressed from the 
sides. The hand is very large, almost quadrate, without 
spines, but closely beset with Gristles along both margins. 
The terminal claw comparatively short. 
The succeeding pairs of legs are exceedingly slender, 
and but sparingly furnished with bristles. The 3 posterior 
pairs are somewhat longer than the preceding, and dis- 
tinguished by the narrow, almost linear form of the basal 
joint. 
The caudal stylets have all about the same appear- 
ance, with slender, lanceolate branches. The last pair are 
scarcely at all longer than the preceding, but have the 
branches somewhat larger as compared with the stem.
