I\^annacara tcenia, sp. n. 



Deptli of body 2| in tlie length, length of head 3|. Snout 

 shorter than eye, the diameter of which is 3| in the length o£ 

 head and equal to the interoibital width. Depth of prae- 

 orbital ^ the diameter of eye. MaxiUary not extending to 

 below eye ; jaws equal anteriorly ; fold of lower lip con- 

 tinuous ; 2 series of scales on cbeek, 1 series on prreoper- 

 culum ; 5 short gill-rakers on lower part of anterior arch. 

 Scales 24: y ; ^ a scale between upper lateral line and dorsal 

 fin for most of its lengtii. Dorsal XVI 7 ; last spine ^ the 

 length of head ; soft lin extending to anterior part of caudal. 

 Anal III 7. Pectoral not quite so long as head ; ventrals 

 extending to vent. Caudal rounded. Caudal peduncle | as 

 long as deep. A dark oblique stripe from eye to inter- 

 operculum ; abroad dark longitudinal stripe from eye to base 

 of caudal ; narrower stripes at edges of series of scales on 

 body; an oblique stripe from eye to interoperculum ; vertical 

 fins dusky. 



A specimen of 42 mm. from the Amazon at Manaos, 

 presented by Herr J. Paul Arnold. Two much smaller 

 specimens (30 mm.) are similar to the type, but are not 

 included in the description. 



The only other species of this genus is Nannacara anomala, 

 Regan, from tiie Essequibo; the types are 55 to 57 mm. in 

 total length, but the eye is larger and the interorbital space 

 narrower (respectively 3i and 4^ in the length of head), the 

 dorsal spines are higher (last more than ^ the length of head), 

 and there are differences in form and coloration also. 



Geophagus pellegrini, sp. n. 



Depth of body 2^ to 23 in the length, length of head 

 2§ to 2|. Snout 2^ to 3 in the length of head, diameter 

 of eye 3 to 4|, interorbital width 4 to 4^, depth of prse- 

 orbital 2| to 3§. Maxillary not reaching eye ; jaws equal 

 anteriorly ; lower lip with a deep lobe on each side ; 

 cheek with 6 series of scales ; 14 gill-rakers on lower part 

 of anterior arch. Scales 31 ^j^, H or 2 between lateral line
