holdsvis betydelig mindre og mere jevnt afrandede. 4de 

 og 5te Segments Epimerer er rettede skraat bagtil og ender 

 med et kort tandformigt Fremspring. 



Øinene er særdeles smaa og dækkes for en stor Del 

 af Pandepladen. De er af smalt kølledannet Form, med 

 den ydre Del kun svagt udvidet og jevnt tilrundet. ( >ie- 

 pigmentet er ganske lyst, næsten kridthvidt og Synselemen- 

 teme kun ufuldkommet udviklede. 



Følerne er ligesom hos Crangoninerne næsten fæstede 

 i samme korizontale Plan, hvorfor de, naar Dyret sees i 

 Protil (Fig. 2), for en stor Del gjensidig (hekker hinanden. 



Iste Par Foleres Skaft (se Fig. 3) er temmelig kort, 

 neppe halvt saa langt som Rygskjoldet. Af dets o Led ei- 

 det Iste storst, og af samme Længde som de 2 øvrige til- 

 sammen. Det er ved Basis paa den ydre Side forsynet 

 med den sædvanlige pladeformige Fortsats. der dog kun er 

 lidet udviklet og af smal lancetdannet Form. Den indre 

 Kant af Leddet er besat med korte Borster og har noget 

 foran Midten et meget lidet tandformigt Fremspring. Sidste 

 Led er noget kortere end 2det og i Enden tvært afskaaret. 

 Af tie 2 Svøber er den ydre hos Hannen omtrent dobbelt 

 saa lang som Skaftet, hos Hunnen noget kortere; den er 

 hos begge Kjøn cylindrisk og temmelig jevnt tyk lige til 

 Spidsen som er udtrukken i en kort Endesnært, samt sam- 

 mensat af talrige korte Led, besatte med de sædvanlige 

 Knipper af klare, baandformige Sandsebørster. Len indre 

 Svobe er (se Fig. 1 og 2) stærkt forhenget, omtrent 3 Gange 

 saa lang som den ydre, og afsmalnes jevnt mod Enden. 



2det Par Følere (se Fig. 4) har en kort og tyk, 

 utydelig segmeriteret Roddel, der saagodtsom ganske er ube- 

 dækket af Rygskjoldet og udåd springer frem i Form af 

 en stærk trekantet Fortsats. 



Det bladdannede Yedhæng er af en ganske usædvanlig 

 Størrelse og saa stærkt udbredt mod Enden, at det i sin 

 normale Stilling ikke blot moder det tilsvarende paa den 

 anden Side. men ogsaa krydser samme (se Fig. 1). Af 

 Form er det næsten trekantet, med den største Brede, der 

 er betydelig større end den halve Længde. i dets yderste 

 Del. Enderanden er næsten tvært afskaaret og viser istedet- 

 for de sædvanlige Randborster kun en yderst tin Ciliering. 

 Den indre Kant er ganske svagt buet og forsynet med de 

 sædvanlige cilierede Randborster, der dog kun er lidet ud- 

 viklede og hurtigt aftagende i Længde mod det indre af- 

 rundede Hjorne af Bladet. Den ydre Kant er næsten lige 

 og ganske glat samt gaar fortil ud i en tandformig Fortsats, 

 der er tæt trykket til Bladet og overrages af Enderanden. 

 Tværs over Bladet lober i diagonal Retning en stump Kjol. 

 der lidt efter lidt taber sig mod det indre Hjorne. 



succeeding epimera (see fig. 2). In the males, these epimera, 

 are. however, comparatively mach smaller and more evenly 

 rounded. The epimera of the 4th and 5th segments are 

 directed obliquelv. in a posterior direction, and terminate 

 with a short dentiform process. 



The eyes are extremely small, and covered to a great 

 extent by the frontal plate. They are narrow and clavate 

 in shape, with the miter portion but slightly dilated and 

 uniformly rounded. The ocular pigment is quite light. 

 approximating a chalky white, and the visual elements are 

 imperfectly developed. 



As with the Crangonians, tin- antennæ are attached 

 almost in the same horizontal plane; and hence, when the 

 animal is viewed in prorile i rig. 2), they cover each other 

 to a great extent. 



The peduncle of the Ist pair of antenna? (see fig. 3) 

 is rather short, scarcely half as long as the carapax. Of 

 its 3 articulations, the Ist is the largest, equalling in length 

 both the otliers tåken together. At its base, it is provided 

 on the exterior side with the usual lamelliform projection, 

 which, however, occurs but slightly developed and narrow- 

 lanceolate in shape. The inner edge of the articulation is 

 beset with short bristles, and exhibits. a little anterior to 

 the middle. an exceedingly small dentiform prolation. The 

 terminal articulation is somewhat shorter than the 2nd. and 

 truncate at the extremity. Of the 2 flagella, the exterior, 

 in the male. is about twice as long as tlie peduncle, — in the 

 female somewhat shorter; in both sexes it is cylindric in 

 form, and nearly of a uniform thickness to the extremity, 

 which is produced to a short terminal lash, as also com- 

 230sed of numerous short articulations, beset with the usual 

 fascicles of translucent, riband-shaped sensory bristles. The 

 inner flagellum (see figs. 1, 2) is considerably elongated, 

 being about three times the length of the outer, and tapering 

 gradually toward the extremity. 



The 2nd pair of antennæ (see fig. 4) have a short and 

 thiek, indistinctly segmented basal portion, leit well-nigli 

 wholly uncovered by the carapax. and, externally, jutting 

 forth in the form of a strong. triangular projection. 



The squamiform appendage attains quite a remarkable 

 size, and is, toward the extermity, so considerably expanded 

 that, in its usual position. it not only meets the corresponding 

 appendage on the opposite side, but even overlaps it (see 

 rig. 1). In form it is almost triangular. with the exterior 

 portion broadest; its greatest breadth considerably exceeds 

 half the length. The terminal border is well-nigh truncate, 

 and exhibits, in place of the marginal bristles usually ob- 

 served, an exceedingly rine clothing of hairs. The inner 

 margin is very slightly curved, and furnished with the usual 

 ciliated marginal bristles. which. however, are but little 

 developed and rapidly diminish in length toward the inner 

 rounded corner of the scale. The outer margin is almost 

 straight and perfectly smooth; moreover, it extends anteriorly 

 as a dentiform projection. closely pressed up to the scale 

 and overlapped by the terminal border. Straight across the 

 scale. extends diagonally an ohtuse carina, which gradually 

 disappears toward the inner corner.
