Bemarls. — The present new genus is founded upon the form, previously 

 described bj' the author as Andania pectinatn. The closer anatomical exami- 

 nation of this form, instituted subsequently', has in fact, shown it to be 

 generically distinct, diiFering, as it does, materiall}- from l)oth the preceding 

 genera, in the structure of the oral parts. The genus comprises, as yet, l)ut 

 a single species.

Body extremely short and stoiit, and apt to be rolled together in 

 the form of a ball. Cephalon with the lateral corners but little projecting 

 and nearly rectangular. First segment of mesosome scarcelj' longer than 

 the succeeding ones. First pair of coxal plates nearly twice as deep as they 

 are broad at the base; the 2 succeeding pairs rather narrow, and transversely 

 truncated at the tip; 4th pair considerably exceeding in breadth the 3 pre- 

 ceding pairs combined, posterior expansion rather large, and obtusely rounded 

 at the tip, distal edge forming a rather slight, and quite even curve. Last 

 pair of epimeral plates of metasome narrowly rounded at the lateral corners, 

 posterior edge somewhat flexuous. Superior antennae with the peduncle rather 

 strong and somewhat flattened, its 1st joint fully twice as large as the other 

 2 combined, flagellum half as long again as the peduncle, with the 1st joint 

 verj' large, longer than the remaining three combined, accessory appendage 

 about half the length of the 1st joint of the flagellum. Inferior antennae 

 considerably shorter than the superior, last joint of the peduncle much smaller 

 than the penultimate one, flagellum scarcely exceeding the length of the 

 former. Gnathopoda with the propodos about the length of the 2 preceding 

 joints combined, that of the anterior ones somewhat dilated in the middle, 

 of the posterior, nearly linear, dactylus in the former armed with 4, in the 

 latter with 2 coarse spines. Last pair of' pereiopoda with the basal joint 

 oval, scarcely exceeding in length the remaining part of the leg, posterior 

 edge smooth, deflexed lobe evenly rounded and reaching about to the middle 

 of the meral joint, the latter much shorter than the 2 outer joints combined, 

 and but slightly produced at the infero-posterior corner. Last pair of uropoda 

 with the rami much shorter than the basal part, outer ramus tbe longer. 

 Telson nearly twice as broad as it is long, tip obtusely pointed and entii-e.
