. The fur seals and fur-seal islands of the North Pacific ocean. Sealing; Seals (Animals). fig. 48. bear a dentigerous ridge. This we have not been able to verify, although on the margin of the lobes we noticed a structure which might be interjireted as a dentigerous ridge, but which appeared to us more like a striation. The ventro-lateral lips do not, upon first examination, show the distinct division into a prominent anterior narrower and a basal broader portion, such as is described for the dorsal lip; lipon careful investigation, however, and especially upon isolation of the cuticle, a bilobed anterior projection may be seen extending into the space between the three lips, similar to but broader than the bilobed anterior portion of the dorsal lip; this projection bears a dentigerous ridge; the base of the lip is about ™™ broad, and the lip is ™™ thick; ordinarily the ventro-lateral lips appear nearly semicircular but asymmetrical in outline. We have not been able to clearly define any dentigerous ridge on the >ase, but we find a number of striae, which might easily be mistaken for such a ridge. The usual papilla is found on the basal portion of each ventro-lateral lip. Intermediate lips are absent; cervical alae absent. The cervical papillae ar. plainly visible ™™ from the anterior extremity. The cuticle of the body is provided with 32 /^ transverse cuticular bauds, apparently without the finer.
