258 Bashford Dean Memorial Volume 



Further, Dean in his first account of Misaki (1901) made the following interesting 

 statement: "In this favorable neighborhood there are several scores of fishermen who are 

 in the habit of supplying the Tokyo market from the deeper waters (300 to 700 fathoms), 

 and there was thus a daily chance for a collector to obtain rare and interesting forms." 

 He stated elsewhere that these men fished with trawl lines which were miles long and 

 carried thousands of hooks. 



For some of the eastern Atlantic specimens we have definite records. No depth was 

 given for the Madeiran fish (Collett, 1890), but for that from the Varanger Fjord, Nor- 

 way, CoUett (1897-1) gave the depth as "some 150 fathoms." Pellegrin and Loppe (1914) 

 had a fish which was taken in an arm of the Gulf of Gascony at a depth not below 200 

 meters — that being the limit for trawlers there. For the waters around the Spanish penin- 

 sula there are several records. Thus the specimen of Carlos de Braganga came from a 

 depth of 580 meters off Cezimbra, Portugal. Bertrand (1926) gave no depth for his 

 specimen taken near San Sebastian, and Lo2;ano Rey made no statement other than that 

 Chlamydoselachus is adapted to deep zones and hence ought to be widespread. 



Along this line of thought, Collett (1897-1, p- 8), in discussing the specimen caught 

 off Madeira, had noted that Chlamydoselachus was thus proved to frequent the waters 

 of almost similar latitudes in the two hemispheres of the globe. Referring to the capture 

 of a specimen in that part of the Arctic Ocean which washes the northern Norwegian 

 coast (74° N. Lat.), he stated that this proves the truth of "the remarkable phenomenon 

 which has often been previously observed and mentioned, that, unaffected by latitude or 

 parts of the Earth, there exist forms of animal life which appear unchanged at great depths 

 in all waters where like temperatures exist, whether under the Equator or up under 

 the Poles." 



Subsequent captures of Chlamydoselachus in the Gulf of Gascony and in the waters 

 surrounding the Iberian peninsula (the deepest from 580 meters) amply justify CoUett's 

 generali2;ations. 



SPECIMENS IN MUSEUMS AND THEIR SOURCES 



For the sake of any readers of this article who may be interested in examining the 

 fish, we list the museums and universities which have or have had specimens, and give 

 the localities whence these were obtained. For European museums (Table I) we have 

 used Collett's list (1897-1) of eleven museums and fifteen specimens without feeling obliged 

 to ascertain if those specimens are still in existence or if others have since been added to 

 these collections. To this list we have added about an equal number of European institU' 

 tions and specimens. Table II for American institutions is, however, brought up to date.
