ARACHNOIDEA. 



CASE crosswise, and drawing the rest after its body. In the length of 

 its hairs and the similarity in size of males and females, it repre- 

 sents in this the Tyroglyphus 

 longior in its genus. Found 

 among Cantharides from Tri- 

 este, in company with Tyro- 

 glyphi. 



There only remains one 

 other Glyciphagus of this sec- 

 tion still to notice, which is 

 remarkable for the peculiarity 

 of its habitat. 



Gj-yciphagus bal^narum, Aca- 

 ridina baloenarum, ( Van Bened. , 

 Bull. Acad. Brux. 1870). 



Glyciphagus spinipes.

M. Van Beneden, in a paper 

 on the cetacea and their para- 

 sites, (loc. cit.) mentions that several individuals of this species 

 were found on a Southern Right whale {Balcena Australis), among 



the cirripeds that incrusted it. He 

 describes it as having the head, thorax, 

 and abdomen, separated from each 

 other, and the body with numerous 

 and long silky hairs, that are plumose* 

 He could not have said in more ex- 

 plicit terms that it was a Glyciphagus ; 

 for these, as the reader knows, are its 

 special characters. No anal appen- 

 dage is represented in his figure, but 

 we know that this only occurs in the 

 females, and the specimen figured by 

 him might be a male, or the posterior termination might not be 

 in a position where it could be seen in the drawing.
