CHLAMYDOSELACHUS ANGUINEUS. 15 
The kidneys were also very long, the right being the longer 
(length 780 mm.) and rather flat, the left being more cylindrical, and 
of a length of 770 mm. Posteriorly, both kidneys form a club- 
shaped, thickened, coalescent portion terminating somewhat abruptly 
towards the anus. The length of the coalescent portion is 120 mm. | 
Entozoa. 
The stomach was empty and did not contain any parasites. 
Amongst the spiral valves, on the other hand, there were hundreds 
of a small Cestoid; it was, besides, occupied by a single short and 
thick Trematoid. 
These two species I forwarded to Dr. Lénnberg of Upsala to 
examine and describe, who in a letter of 15 March 1897, gives the 
following information: — 
The Cestoids belong to the genus Monorygma, but form a new 
species, for which he has proposed the name M. chlamydoselachi.” 
The Trematoid is probably Distomum veliporum. 
Chlamydoselachus anguineus (,the snake-like frilled shark“) is 
without comparison the most lengthy of all existing sharks. When 
one regards the eel-like construction of its body, the almost serpentine 
head, its deeply cleft mouth, the frilled and protruding gill coverings 
and its formidable array of teeth which call to mind the python’s, 
one’s thoughts turn to that mythical creature, which with more or less 
regularity is annually described or even depicted in the columns of 
newspapers; whose existence, however, has never been confirmed; but 
which, as a rule, is believed in by all (except by naturalists), namely 
1 Of the genus Monorygma there were, according to Dr. L., but two hitherto 
known species. One of these, M. perfectum,.v. Ben., is ten times as large as 
the new species, and occurs in the intestines of Somniosus microcephalus, (BI. 
Schneid.). This species has, too, been found by Dr. L. in specimens from 
Norway. The other species, M. elegans, Mont., resembles the new one in size, 
and has been found in the Scylliwm-species in the Mediterranean.
