^^IS,.] XPAY SPECIES OF nSIIES. 36l . 



a. M. notata, Tliis species, which I observed at 

 GuBclaloupe, has some resemblance to the preceding 

 in its narrow opercnla, but it is principally cUstingaish- 

 cd by the following characters : 



Its dorsal-fin is longer than high, and terrainated 



by a shorter posterior ray than in the foregoing, ^v hich 



ray does not pass beyond the centre cf the interval 



^comprehended between this fm and tlie baye of the 



caudal-fin ; sides not striped ; opercnla oblique. 



Back almost straight; thorax and abdomen arcuated, 

 cavinated; body six times the length of the head, in depth 

 about ^ head and a half ; maxillames prolongated un- 

 der the eyes ; anal-fi.n narrow, equal throughout, more 

 apparent than in the preceding, but much less so thaij 

 iii the C. thrissa cf Eloch : ventrals smsdl^ truncated ; 

 scales large ; hack blue, without blackish band*, hJ 

 ornamented v/ith fine blue spots ; sides of a pale blue 

 colour ; abdomen and head white ; total length of in- 

 dividual from six to eiglit inciies. 



The individual abovfc described was taken in a 

 seine, with several other species of different genera, at 

 a village named Pigeon, situate on the seaside, in t\m 

 Island of Guadaloupe. I was only allowed a few 

 moments to sketch and examine it, as I was at ih% 

 point of departure for Bas&eterre. I cannot ^nA it 

 described in any author to v/hich I have access.
