 (Plate XXXVII.\) 



Phractura aivSorgii. (Plate XXXVIl. Bg. 1.) 



Depth of body 10 times in total length, length of head 5 times. 

 Head 1| as long as broad ; skull rugose, covered with thin 

 skin ; a median ridge on the snout, bifurcating towards the 

 interorbital region ; snout a little longer than the postocular part 

 of the head, pointed, projecting beyond the mouth ; anterior 

 nostril three times as distant from the end of the snout as the 

 posterior from the eye ; eye supero-lateral, its diameter 7 times in 

 length of head, If in interocular width ; maxillary barbel h length 

 of head, mandibulars shorter. Occipital process twice and a half 

 as long as broad, narrowly separated from interneui'al shield. 

 Dorsal I 6, first ray longest, as long as head ; second dorsal very 

 small. Anal 1 10. Pectoral as long as head, nearly reaching base 

 of ventral ; latter a little shorter, nearly reaching anal. Caudal 

 with crescentic notch. Caudal peduncle a little depressed, \ total 

 length. 26 dorsal and 22 ventral scutes, the last 11 on the 

 caudal peduncle. Pale brownish above, speckled with blackish, 

 white beneath ; two small blackish spots on the dorsal and two 

 blackish streaks aloug the caudal. 



Total length 46 millim, 



A single specimen from Agberi, obtained in September 1901, 

 along with other small fishes, by means of a native fishing-basket 

 dipped in shallow creeks and flooded yam-plantations. 



This is the third species of the genus Phractura Blgr., previously 

 known from the Congo only. It differs from both P. bovei 

 Perugia, and P. scaphirhynchura VailL, in the greater number of 

 rays to the anal (11 instead of 8), and of scutes on the bodj^ and 

 caudal perluncle, and in the posterior nostril being much nearer the 

 eye ; from P. hovei in the much larger eye. 



FuNDULtrs GUiiABis. (Plate XXXYII. figs. 2 & 3.) 



Depth of body equal to, or a little less than, length of head, 

 3i to 4 times in total length. Snout as long as eye ; lower 

 jaw but feebly projecting beyond the upper ; diameter of eye 

 3| to 4 times in length of head, twice in interorbital width. 

 Dorsal 15-16, originating at nearly equal distance from the 

 head and from the base of the caudal, longest rays about 

 I length of head in females, | to | in males. Anal 16-18, opposed 

 to dorsal, the rays about as long as those of the latter. Pectoral 

 nearly | length of head, in males reaching beyond base of ventral
