. IDom. Fig. 10 cm Fig. 2. Fig. I. Dorsal view of skull, the numbers refer to the numbered measurements in the text. Fig. 2. Nasopharyngeal area of skull, the number refers to the measurement bearing the same number. MALE SKULLS (Plates VIII, IX and X) The twenty-eight male skulls vary in length from 313 to 416 mm., and include repre- sentatives of the stages from the first year to full growth and maturity. Ossification never reaches the advanced condition found in some Pinnipedia where the skull may become an almost solid mass of bone. It is no more developed in 4 of 416 mm. than it is in 662 which is 25 mm. less. The observable fusions are those of the cranium, in the region of the alveolar parts of the maxillae and premaxillae where they are in contact, and in the maxillo-palatine sutures, but the last are fused in only two male skulls and both of them of the largest size.
