After Garman, , Fig. 2, pi. be seen upon comparing Text'figures 37 and 38. There are differences in the number, si7;es and shapes of the basal cartilages, particularly the mesopterygium. In Carman's figure this is triangular in outline, in Braus's figure it is more nearly quadrangular. The anterior radials are fused over a considerable area in Braus's figure, but exhibit a more limited amount of fusion in Carman's figure. In Braus's specimen, many of the radials posterior to the region of fusion have four or five segments; in Carman's specimen, there are nowhere more than three segments of a single radial. Deinega's Fig. 14, Taf. IV, portraying a pectoral fin (aspect not stated) of Chlamydoselachus closely resembles Carman's figure (my Text-figure 37) save that right and left are reversed. Deinega's Fig. 15, Taf. IV, representing an inner (ventral) view of a pectoral fin of Chlamydoselachus, more nearly re- sembles Braus's figure (my Text-figure 38) which is also a ventral view. The chief differences in the fig- ures thus far considered are understandable on the assumption that Carman portrayed a dorsal view, and that Deinega's Fig. 14 is also a dorsal view. In Deinega's figures of the pectoral fin, some of the lines at the distal margin are so indistinct that one cannot determine the exact number of cartilaginous elements; but in his text he states that there are three rows of radial segments.
