same rays, and here they seem to be longitudinally divided. 

 They appear to form a feeble anterior dorsal fin. 



Through a fracturing of the snout some of the teeth, ap- 

 parently those of the splenial bone, are exposed. The rows 

 cannot be counted, but the teeth themselves are very much 

 smaller than those of Coccodus armatus. At the tip of the 

 lower jaw is seen a small, conical, pointed tooth. 



The specimens are from Hakel. 



Coccodus insignis, sp. nov. 



Plate XXIX, Figures 2-5. 



Of this species there are in the collection several specimens, 

 all from Hajula. The following six are especially to be 

 mentioned: Nos. 4516a (3666), 45166 (3700), 4516c (3701), 

 4Si6J (3702), 4516^ (3703). and 4516/ (3794)- Of these. No. 

 No. 45166 (3700) and No. 45i6<i (3702) are to be regarded as 

 the types. The former consists of a somewhat damaged fish 

 which has been flattened from above downward, and may be 

 taken as showing the form of the fish when seen from above. 

 Only the tip of the tail fin is missing. The total length is 

 80 mm. On each side is seen a broad, hooked spine, a part of 

 the shoulder girdle. The head is pointed in front, and it and 

 the anterior body region expand backward to the ends of the 

 spines mentioned, so as to be wedge-shaped. These lateral 

 spines appear to be much broader than the corresponding 

 ones of C. armatus, as figured by Davis (Trans. Roy. Dublin 

 Soc, III, pi. XXX, fig. i) and Woodward (Cat. Foss. Fishes, 

 III, p. 267). The anterior, or outer, border of each is finely 

 denticulated. The upper and lower surfaces are ornamented 

 with fine ridges, which start from the base and converge to 

 the point. Anteriorly these ridges become tuberculated. In 

 front and behind, the base of each spine passes into anterior 

 and posterior processes of the pectoral arch. Lying in the 

 curve of the hinder border of the pectoral spine and on the 

 matrix from which a portion of the spine has been removed 

 are seen abundant remains of pectoral fin rays; but these 

 have been much disturbed. The ravs of the dorsal are so
