in the M. longimana ; the radius stout, expanded at the ends, the ulna 
shorter, more slender, curyed and with an olecranon. The metacarpi, or 
the first series, are quite elongate, except that of the upper (inner) digit, 
which is stouter. If there were six digits in the second digit (third), the 
limb measured 8 feet 4 inches, but if, asin M. longiémana, there were 
eight, it equalled the cranium in length (9 feet).

The simple headed first rib indicates the generic relationships to be 
with Megaptera, as does the entirely simple scapula. 
In reply to my enquiries, Dr. Gots gives the following account of the 
external appearance of this whale. The dorsal outline is strongly con- 
vex, and it is questionable whether a dorsal fin exists, as he had not seen 
it on two specimens from the decks of the vessels to which they were fast- 
ened. The color is sooty black above, the breast, belly, and under sides 
of pectoral fins milk white, marked with scattered black spots or dots. 
The condition of the specimen allows of an exact comparison with the 
species of this genus already known from the Atlantic Ocean. The 
skeletons of the two Pacific species, are unfortunately unknown, so that 
comparison with them cannot be made. 
From WM. lalandii of the Cape seas, it may be at once distinguished by 
its lack of acromion process on the scapula. Cuvier, who figures the 
Cape species, * does not indicate the deep occipital groove, but rather a 
keel without lateral protuberances, a difference too marked to be de- 
pendent on age; his orbital plates of the frontal are considerably narrow- 
er, and his fourth cervical bears no parapophyses. He does not figure such 
a prominent coronoid process. The coloration of this species is much 
like that of the West Indian whales.
