na a baleen is black? Cervical vertebre separate. Second 
lateral process very large, third, fourth and fifth large, ringed, 
sixth very imperfect, upper process elongate; bent down, lower 
short, rather depressed, seventh upper process elongate, lower 
wanting. The third and fourth cervical thinnest and of nearly 
equal thickness, fifth rather thicker, sixth thicker still, seventh 
thickest, and the thoracic vertebree becoming gradually thicker. 
Ribs 15°15, first narrower at the vertebral end, second, third and 
fourth dilated and produced on the inner side of the vertebral 
end, rest simple. Chest-bones in three series, first simple, second 
larger with processes, third cordate with the first pair of ribs on 
the hinder end. Vertebre: 10 caudal, 15 with chevron, 17 lum- 
bar, 15 thoracic, 7 cervical. 
+ The transverse apophyses of the cervical vertebre short; of 
_ the third, fourth, fifth and sixth, separate at the ends. Ror-

_ The transverse apophysis of the second cervical vertebra thick, 
short, converging, but separate at the end; of the other cervical 
yertebre slender, ‘rather longer, far apart. The upper apophysis 
of the sixth bent down, rather elongate ; the lower one thicker, 
; shorter, and bent up at the end.

_ The length is 38 feet ; the head is 9 feet long; the vertebre are 
60 in number, and there are 15 pairs of simple ribs. 
a cervical vertebre are all separate, and nearly equally de- 
ped ; the bodies of the cervical vertebrz are squarish oblong, 
about + broader than high ; the spinal canal is oblong depressed, 
‘twice as wide as high; the second 1s twice as thick as the other, 
with two large, broad, lateral processes, scarcely as long as half 
the width of the vertebra, coming together at the end, but sepa- 
rate, and leaving an oblong hole between them. The third, 
fourth, fifth and sixth cervical vertebre, each with superior and 
inferior narrow lateral processes, the upper one of the third bemg 
= narrowest, and gradually increasing in thickness to the sixth. 
ae lower of the fourth rather the broadest, and of the sixth the 
ickest and most tapering at the end. The third, fourth, fifth,
