The T^atural History of the Frilled Shar}{ 



253 



Our next reference to the taking of Chlamydoselachus in Japanese waters is from Dof' 

 lein's book of travels in the Orient (1906). He stated that "On the Odawara ground, the 

 rare Chlamydoselache angmnea is caught in winter, that shark with the three-pointed 

 teeth whose nearest kin are known to be of the Cretaceous period." This matter-of-fact 

 statement would indicate that, thanks to Dean's employment of Kuma and other fisher- 

 men, the fish was becoming well known. Doflein's excellent figure is reproduced herein 

 as Figure 2, plate I. 



There is before us a price list of 895 different species of Japanese fishes, issued by Alan 

 Owston of Yokohama in 1905. In this he quoted '^ Chlamydoselachus anguineus, 100-200 

 shillings" ($25-$50). From this, one may judge of the relative facility with which this 

 rare fish could be procured 28 years ago. In fact it would seem that Owston and Japanese 

 dealers carried on a regular business in handling specimens of Chlamydoselachus, for in 

 every article but one quoted herein, dealing with the internal structure of this shark or with 

 its embryos, if any statement is made as to the source of the material, Japan is always 

 named.

Furthermore, Japan has been the source of the greatest number of museum speci' 

 mens, mounted or unmounted, as will be shown in tables later. Of the former, the only one 

 figured, so far as we know, is in the Senckenberg Museum at Frankfurt am Main. This 

 has been described by Mertens (1921). That it may be compared with the other figures, 

 his drawing is reproduced herein as Text-figure 4. This specimen is a female and measures 

 about 1585 mm. (62.4 in.). 



Since the above was written, the American Museum has received from the Japanese 

 Fisheries Society volume I of an elaborate work, ''Illustrations of Japanese Aquatic 

 Plants and Animals" by Kumataro Ito, published in 1931. On PI. IV, fig. 3, of this 

 volume, Chlamydoselachus is represented in color. This illustration is reproduced herein 

 (from a photograph) as our Text-figure 5. Our discussion and criticism of this figure will 

 be found later in this article in sections dealing with the various structures. The short 

 descriptive text gives no new data whatever, and we are not able to state whether this 

 figure was made from a fresh or from a preserved specimen; possibly it was copied from 

 some other drawing.

 burg, Pennsylvania, has returned from the Misaki station, bringing to the Museum an
