it may be described as Arcturus corniger^ taking its specific 

 name from its numerous horn-like protuberances, seven of 

 which surmount as many separate segments ; while the fourth 

 segment carries no less than six cone-like swellings, the two 

 largest of which are on the median line of the back, the front 

 one being preceded, and the hinder one in like manner fol- 

 lowed, by a smaller flanking pair of heights. 



The upper antenna? extend only as far as the second joint of 

 the lower ones ; they are slender and ajiparently three-jointed, 

 the last articulation being the longest and ending obtusely. 

 The lower antenna? are stout, and equal in length to half that 

 of the rest of the animal : the second joint is notched ; the 

 fourth joint is considerably the longest ; the third and fifth 

 are also long and about equal in size. The eyes are promi- 

 nent. The marsupial pouch of the fourth segment has a row 

 of tubercles just below the hinge-line ; and in the rear 

 of this, three small apertures are visible in the ventral 

 surface. 



The Rev. A. M. Norman kindly informs me that the draw- 

 ing of this species which I sent him comes near to Leachia 

 nodosa of Dana, but that he should hesitate to unite the species 

 on the evidence of the_ figures which he has seen, the 

 spiny processes on the segments being somewhat differently 

 arranged. 



Of fig. 3 four specimens occurred, obviously belonging to 

 the same genus as fig. 2. Three of these had masses of red 

 granular matter clinging to the lower surface ; but whether 

 this consisted of the eggs or of some extraneous substance it 

 is not easy to say. All these four lie flat, in a posture very dif- 

 ferent from the strange angularity shown hy Arcturus cor uiger 

 in common with our British Arcturidfp : neither do they pos- 

 sess any remarkable protuberances ; the segmentation, how- 

 ever, is the same. The anterior legs are slender and ciliated, 

 the three hinder pairs being stout by comparison, though not 

 absolutely very robust. The upper antenna? extend beyond 

 the second joint of the lower, and terminate in a point. The 

 lower antenna? display a prominent angle on the second joint ; 

 the third and fourth joints are each respectively longer than 

 those which precede them ; the fifth is not quite so long as 

 the fourth. The fourth segment of the body, viewed from 

 above, is coffin-shaped, and has two small tubercles on the 

 median line. The eyes are prominent. The wliole length, 

 antenna? included, is about half an inch. The colour of the 

 specimens is a more or less purplish brown, closely speckled 

 all over with dark spots. Arcturus Jineatus may be offered m 

 a specific name for these creatures, as they seem to hold
