the head one-third. Snout obtuse, not much longer than the eye ; 

 cleft of the mouth small, the maxillary extending to the vertical 

 from the anterior margin of the orbit. Lips thick ; a pair of pores 

 on the symphysis of the lower jaw, a central groove behind it. Snout 

 naked, the remainder of the head being scaly. The width of the 

 interorbital space is much less than that of the orbit. Dorsal and 

 anal spines exceedingly strong ; the third of the dorsal fin is the 

 longest, and nearly two-thirds as long as the head. The second anal 

 spine is much longer than the third, and a little shorter (but stronger) 

 than the third of the dorsal fin. Each ray of the soft fins is accom- 

 panied by a series of minute scales, but only on the caudal fin are 

 these scales dense enough to cover the rays. Caudal fin slightly 

 emarginate. Silvery, with four black cross bands : the first runs 

 from the occiput through the eye to behind the angle of the mouth ; 

 the second from before the dorsal fin to below the base of the pec- 

 toral ; the third from the base of the sixth, seventh, and eighth 

 dorsal spines to the vent ; the fourth descends from the origin of the 

 soft dorsal to that of the soft anal. Fins blackish. 



Only one specimen, 8^ inches long, is in the collection. 



7. PoLYNEMus APPROxiMANS (Lay & Bennett ?). 

 0.71^3. A.^. L.lat.60. 



8. Caranx, n. sp. There is a young specimen in the collection 

 which appears to belong to an undescribed species closely allied to 

 C. Carangns and C. Hippos. 



9. Caranx leucurus, n. sp. 



D. 8|^. A. 21^^:1:^. Very closely allied to C. bicolor. The first 



dorsal fin is composed of short, stoutish spines, the fourth of which 

 is the longest, but scarcely longer than the eye. The soft dorsal and 

 anal are rather elevated ; the caudal is emarginate, and has the lobes 

 rounded. Teeth very small, forming a single series in both jaws ; 

 palate smooth. The height of the body is one-half of the total 

 length (without caudal), the length of the head one-third. Snout 

 rather obtuse, the jaws being equal in front when the mouth is 

 closed ; the maxillary extends to below the anterior margin of the 

 orbit. The lateral line makes anteriorly a subsemicircular curve, 

 the width of which is contained from If to 14 times in the length of 

 the straight portion ; it becomes straight behind the vertical from 

 the origin of the second dorsal, and is armed with about fifty small 

 and low shields, only a few of which terminate in a depressed spine. 

 The pectoral fin extends to the anal spines. Brownish grey, body 

 with six dark-brown vertical bands : the first crosses the body behind 

 the base of the pectoral, and the fourth descends from the middle of 

 the soft dorsal fin. Operculum with a large black spot. Dorsal, 

 anal, and ventral black ; pectoral and caudal whitish. 



Only two young specimens are in the collection, the larger being 

 3 inches long.
