GEN. PYLOPAGUEUS, A. Milne-Edwards and Bouvier. 



1891. Pylopagurus, A. M.-Edw. and Bouvier, Bull. Soc. Philom., 



Paris, Ser. 8, vol. iii., p. 108. 

 1905. P., Alcock, Catal. Indian Decap. Crust., pt. 2, fasc. 1, p. 189. 



PYLOPAGURUS UNGULATUS (Studer). 



1883. Eupagurus ungulatus, Studer, Abhandl. k. Ak. Wiss. Berlin, 



1882, p. 26, pi. 2, figs. 13, a, b, c. 



" One specimen was found at the entrance to Table Bay, 

 Cape of Good Hope, in 50 fathoms [94 m.] depth. The 

 animal occupies the shell of a Fusus ; this is so completely 

 invested by a red Eschara, that about the mouth of the 

 mollusc only a little oval opening is left, which can be 

 completely closed by the seal-like hand of the crustacean's 

 right cheliped." 



1893. Pylopagurus u., A. M.-Edw. and Bouvier, Mem. Mus. Comp. 

 Zool., Harvard, vol. xiv., No. 3, p. 80, pi. 6, figs. 15-18. 

 The authors, however, point out several features in which 

 their species from the Yucatan Bank differs from Studer's 

 South African specimen. 



FAMILY CCENOBITID^. 



1888. Ccenobitida, Henderson, Challenger Anomura, Eeports, vol. 



xxvii., p. 49. 



Dana, Stimpson, and Haswell use the form Cenobitida, 

 which, as will be presently explained, is incorrect. 

 1905. C., Alcock, Catal. Indian Decap. Crust., pt. 2, fasc. 1, pp. 138, 

 192. 



GEN. CCENOBITA, Latreille. 



1829. Canobita, Latreille, Regne Animal, vol. iv., p. 77. 



Already in 1825 Latreille, Families naturelles du Regne 

 Animal, p. 276, defined this genus, and on p. 277 gave its 

 name in French as Cenobite, but he did not supply the 

 scientific version of that name, Ccenobita, till 1829. Subse- 

 quently Milne-Edwards, Dana, and others used the form 

 Cenobita, which is a mongrel between Latreille 's French 

 and Latin denominations.
