outwards, and i3ar% lie flat on the scales ; tlioy are stout, i Jotli 

 of an inch in breadth, slightly arcuate, pointed, and ornamented 

 with several rows of distant minute tubercles ; to the inner aspect 

 of the notopodia is attached the hemj^-like hair which covers the 

 scales. The ventral cirri are very small, and consist of a thick 

 proximal, and a slender distal portion. The surface covered with 

 minute papillro. Tlie scales are very delicate and semitransparent. 

 The total length is about an inch, the breadth about a } of an 

 inch. 



Two specimens of this species were obtained with the dredge 

 at a depth of 15 fathoms in Port IMoUo. One of tliese I dissected, 

 and noted the following peculiarities : — 



There are no teeth, but otherwise the oesophagus and the major 

 portion of the muscular gizzard (pi. viii., fig. 1) very much resemble 

 those of Pohjnoc ; the epithelium (pi. vii., fig. 11) consists of 

 cells filled with granular material, having a tolerably broad base 

 where they abut on the cuticle, but tapering externally into a 

 slender thread ; between those slender external prolongations 

 of the epithelial cells are a number of irregularly arranged nuclei 

 and pigment granules. Towards its posterior end the crop 

 becomes much narrower, and the epithelial lining becomes thrown 

 into a series of regular ridges, presenting the appearance shewn 

 in fig. 12, the ridges being separated by furrows in which the 

 epithelial lining is very thin ; the cells constituting those ridges 

 (fig. 13), £.re much longer than in the epithelium of the anterior 

 j)ortion of the crop, but present the same general characters. 

 The anterior portion of the intestine is very wide, and the hinder 

 portion of the crop is completely embraced by it for a little 

 distance. The rest of the intestine, however, is a narrow tube 

 giving oflt complex cpocal appendages. The ceeca (pi. viii., fig. 2) 

 which are given off from the dorsal aspect of the intestinal tube, 

 and begin in the second or third segment, have a Jiong narrow 

 neck, giving off numerous branches, each of which ends in a slight 

 dilation filled with '' hepatic" cells.
