16 DR. H. J. HANSEN ON THE 



Maxillce (secoud pair of maxilli©, auct.) (PI. 4. fig. 2,?m; fig. 5). — 

 These are somewliat shorter than the raaxillulse, but yet rather 

 large. They differ from those in Eurydice only in one point : 

 the lobe of the third joint {P) is a single moderately broad i)late, 

 Avhile in Cirolana-Eurydice it is divided into two parallel lobes, 

 together as broad as, but proportionately longer than, that in 

 Anuropus. The lobe of the secoud joint has four long and strong, 

 plumose seta?, the lobe of the third joint four shorter setfe. 



Paragnatlia (or hjpopharynx) (PI. 4. fig. 2Jc). — These are a pair 

 of plates which are turned strongly outwards ; each is a little longer 

 than broad, Avith the anterior margin rounded. As compared 

 with those in Glrolana, they are a little broader and very much 

 shorter, turning considerably more outwards, and without any 

 produced and curved terminal portion. 



Maxillip)cds (Pi. 4. fig. 2).~These are thick, do not reach the 

 distal end of the outer lobe of the maxillulse, and they are in other 

 respects very reduced. The basal joint {n) and its large epipod 

 (o) as developed as in Oirolana. The second joint is formed by 

 the fusion of the second and third joints in Girolana ; it is 

 moderately short, and does not possess any trace of the lobe 

 (frequently with coupling-hooks) developed in Girolana-JEurydlce. 

 The palpus consists in Girolana and closely allied genera of four 

 joints ; in Anuropus all these have been completely fused without 

 traces of sutures, constituting one large oblong joint, with some 

 short setse on the lower side near the inner margin ; and this 

 joint shows even tolerably the general outline of the four-jointed 

 palpus in the genera mentioned. 



Thorax and its Leys. — Figs. 1 and 2 in Beddard's work convey a 

 sufficient idea of the shape of the thorax with its " epimera" ; it 

 scarcely needs mention that the suture, drawn in his fig. 2, between 

 the first segment and its epimerou does not exist. The fii-st pair 

 of legs (PI. 4. fig. 6) are very robust, to a certain degree developed 

 as a prehensile organ; the third joint (the not-developed epimeron 

 considered as the basal joint) is thick, the fourth short and thick, 

 the fifth very short, the sixth rather long and thick ; the seventh 

 joint (7) is nearly claw-shaped, but yet slightly curved, and can 

 be folded inwards along the lower surface of the sixth joint ; it 

 terminates in a real claw (c), which is exceedingly short, acute. 

 Of the six other pairs of legs only one leg, of the fourth pair, was 

 almost completely preserved, and it agrees in all essential points 

 with the same leg in some species of Girolana ; its fmir distal
