large, subequal in length and broader than 6th, peraeopods not very 

 slender, telson not very elongate, cleft for less than half its length. 



The institution of a new genus for the present species seems justified 

 in view of the fact that the 4 new species of Cleonardo described by 

 Chevreux (Bull. 1'Inst. oc. Mou. no. 121, p. 1) all agree in possessing 

 the same generic characters as the original species, C. loncjipes Stebbing, 

 The telson is somewhat similar to that of Bozinante Stebb., but in this 

 genus the 5th joint of the gnathopods is not lobed. 



CLEONARDOPSIS CARINATA n. sp. 

 (Plate XXVII. Figs. 7-9.) 



Body carinate, keel very low on the 5 anterior peraeon segments, 

 on peraeon segments 6 and 7 and pleon segments 1 and 2 increasing 

 in height posteriorly and ending in an acute tooth, on pleon segment 

 3 highest in the middle, thence descending to posterior end where there 

 is an acute, forwardly directed, curved tooth, pleon segment 4 smooth, 

 not depressed. 



Head with very short depressed rostrum, antero-lateral angles 

 truncate, eyes not apparent. Side-plate 1 not produced forwards, 

 short, 2-4 increasing in length, inferior margin straight, antero- and 

 postero-inferior angles rounded, side-plate 4 moderately emarginate, 

 5 bilobed, posterior lobe rather deeper and apex subacute, 6 sub- 

 rectangular, antero-inferior angle bevelled off, deeper than long, 

 7 trapezoidal, longer than deep, not deeper behind than in front. 



Pleon segments narrowed and rounded below, postero-lateral angles 

 of 2nd and 3rd quadrate, with slightly produced acute point in 2nd, 

 well produced in 3rd. 



Telson short, not reaching beyond |. length of rami of uropod 3, 

 somewhat pyriform, cleft -^ its length, apices obtuse, non-dehiscent, 

 unarmed. 



First antenna reaching to 2nd pleou segment, 2nd joint | length of 

 1st, 3rd joint not -] length of 2nd, flagellum longer than peduncle, 

 ca. 70- jointed, accessory flagellum small, 1- jointed, f length of 1st 

 flagellar joint. 



Second antenna in <$ as long as first antenna, in $ extending to 

 middle of peduncle of first antenna, ultimate joint shorter than 

 penultimate, flagellum longer than peduncle in <$ , nearly equal in ? , 

 ca. 60-jointed in <^, ca. 20-jointed in $ . Flagella of both antennae 

 calceoliferous. 



Upper lip broader than long, distal margin rounded, entire. 



Lower lip more resembling that of Cleonardo neuvillei Chevreux
