30 EXPEDITION TO JAPAN.

Concer HAMO, Temm. and Schleg., Fann. Jap. Pisces, p. 262, pl. 114, f. 2. 
Nores.—F rom Simonda, (length four fect.) 
The drawing is colored over the back of head and body of a rather uniform dusky slate, with 
tinges of olive, lower parts nearly white. Irides silvery. Pectorals like back. Dorsal and 
anal darker along the margin. 
In the Fauna Japonica it is said to attain a length of ten feet. The authors had received it 
also from the Straits of Sunda, and consider it different from the C. Tala-Bon of the same 
locality. Dr. Kaup, in his ‘‘ Uebersicht der Aale,’’ in the Archiv fiir Naturgeschichte, 1856, 
part 2, p. 74, places the Zalabon in the genus Muraenesox of McClelland, where this species 
also belongs. Bleecker, in his Nalezingen op de Ichthy van Japan, p. 54, seems to suppose that 
the Hamo is the same as the C. bagio of McClelland. Under the name of FYammo this fish is 
probably the one copied in Kaempfer, plate XII, No. 4. 
52. ANGUILLA MYRIASTER, N. S. 
PLATE XI, fig. 2. Reduced. 
Nores.—l'rom Hakodadi. (Length 22 inches.) 
This distinctly marked species seems to be entirely new. It may be the Congre a chapelet of 
Cuvier, so named from a figure of Krusenstern’s Atlas, pl. 60, fig. 7—a reference which could 
not be consulted.—(See note at foot of page 262 in the Fauna Japonica.) 
In its general appearance and form it resembles a common eel, and probably belongs to the 
genus Anguilla. Snout to tip of caudal 22 inches. Snout to eyes } inch. Eyes ;5; inch. Snout 
to pectorals 34 inches. Pectorals 1} inch. Snout to origin dorsal 4} inches. Snout to origin 
anal 94 inches? Height of body about 1} inch. Dorsal rising very gradually, and highest 
near the caudal. Anal of sub-equal height. 
Colors.—Rich wood-brown over the back, shading off lighter, but in blotches, below the 
lateral line. Snout and head to back of eyes, and all the lower parts of the head and body of 
a very pale slaty-blue tinged with brown towards caudal. Ivrides silvery. Dorsal of a pale 
dusky slate, becoming more bluish towards caudal, and with a narrow margin of dark dusky 
along its whole length. Towards the caudal, where the dorsalis higher, this margin is broader, 
and shades off less abruptly. Anal of same color as the lower parts of the body, but towards 
the caudal it has a margin like the dorsal. The most distinctive markings of this eel, however, 
consist in two regular series of snow white spots or dots on each side of the back, commencing a 
short distance back of the eyes and running nearly to the caudal, becoming fainter as they 
approach it. The uppermost series consists of very small dots about the diameter of the eyes 
apart and set in very regular order, dropping a little, however, as they recede from the head. 
The second series is composed of spots of twice the size of the first, much more closely set, and 
apparently following the lateral line. Towards the caudal they seem to form a broken white 
stripe only. The engraving represents the appearance of these spots very accurately as they 
are given in the original drawing.
