REPORT ON THE AMPHIPODA. 959 



Genus Cleonardo, n. gen. 



Near to Khachotropis, S. I. Smith. 



Antenna.' subequal, the upper longer than the lower. 



Upper Lip with the distal margin convex. 



Palp of the Mandibles long and slender, the third joint longer than the second. 



The outer plate of the First Maxillse carrying eleven spines ; the two-jointed palp 

 very long. 



The inner plate of the Second Maxillse much broader than the outer. 



The calx of the wrist in the two pairs of Gnathopods not much produced. 



The Perieopods all very long and slender, especially the fingers, which have setae on 

 the outer margin. 



The outer ramus shorter than the inner in each pair of Uropods. 



TJie Tel son long and deeply cleft. 



The trunk without carina or processes. 



The generic name is taken from a personal name in Don Quixote. 



From the species that have been assigned to Rhachotropis (under the name Tritropis), 

 the species on which the present genus is founded differs in some particulars not included 

 in the generic character ; thus the side-plates of the first four peraeon-segments are not so 

 small, nor is the first pair produced forwards ; the third joint in the first and second 

 pairs of perseopods is not short, but elongate, while it is comparatively short iu the 

 three following pairs. 



Tritropis appendiculata, G. 0. Sars, 1 must no doubt be referred to this genus. 

 That species was obtained in the sea north-west of Finmark, at the depth of 1287 

 fathoms, at a station located in the cold area. In 1885 Sars remarks upon it, "the form 

 treated of here exhibits in some respects a rather striking deviation from the other 

 species referred to the genus Tritropis, and may possibly be found to constitute a 

 separate genus." 



Cleonardo loncjipes, n. sp. (PI. LXXXVL). 



Rostrum short and broad but well pronounced, sides of the head with broadly 

 rounded lobes. The skin microscopically furred. 



Eyes not perceived. 



Upper Antennas. — First joint of the peduncle much stouter than the second, outdrawn 

 below into a blunt point, tipped with one very short and one rather longer spine, and 

 two feathered spine-like cilia ; the second joint rather longer than the first, distally out- 

 drawn to a point above and below, with feathered cilia preceding the outdrawn parts ;
