in each of the segments of the me.sosoiue, formed a double transversal band. 

 The eyes were of a deep purplish brown colour. The incubatory pouch of 

 most of the females was greatly extended, and tilled with a very great num- 

 ber of eggs or yoixng ones.

Remarks. — As this name had l^een approjn'iated in Zoology at an 

 earlier date, M. Bonnier has recently proposed to change it to Normanion. 

 The sexual difference in this genus is very slight.

During my investigations in tlie Trondhjemsfjord, I found this form 

 in great abundance clinging to the skin of fishes (both living and dead) 

 caught on a fishing-line set in deep water. The parasitic nature of this ani- 

 mal, alread}' indicated by the peculiar structure of the oral parts and of the 

 anterior gnathopoda, has thus been ascertained.

Very like the tj'pe species as to outward appearance, but of somewhat 

 larger size. Eyes very large and confluent, occupying nearly the whole sur- 

 face of the cephalon. but having the visual elements imperfectly developed, 

 pigment light reddish brown, and slightly areolated. Antennae of a similar 

 structure to that in N. qiiadrimaniis, though with the flagella somewhat 

 more elongated, and each composed of 6 articulations; accessory appendage of 

 the superior ones 4-articulate. Anterior gnathopoda rather large, with the 

 basal joint somewhat Hexuous and occupying half the length of the leg, ischial 

 joint elongated to an unusual extent, carpus forming below a comparatively short 

 and obtusely rounded expansion, propodos much broader than it is long, with the 

 upper face very short, the lower lioldly curved, palm transverse and defined 

 below by a dentiform projection with a comparatively small spine on each 

 side, dactyhas rather slender and perfectly smooth. Posterior gnathopoda, 

 pereiopoda, uropoda and telson nearly as in the type species. Body pellucid, 

 with a pale yellowish tinge, and exhibiting on each side, above the insertion
