DIOGENES MILES (Fabricius). 



1787. Pagurus miles, Fabricius, Mantissa Insectorurn, vol. L, p. 327. 



1791. Cancer m., Herbst, Krabben und Krebse, vol. ii., pt. 1, p. 19, 

 pi. 22, fig. 7. 



1843. Pagurus m., Krauss, Siidafrik. Crust., p. 58. 



" This species is very common on the sandbanks of Natal 

 Bay, and occurs in all sizes in the shells found there, especially 

 in Natica mamilla L., Buccinum arcularia L., Murex, Pyrula, 

 Trochus and Nassa. The colour is dusky yellowish with 

 brownish longitudinal stripes on the two front feet. My 

 largest specimens are not over two inches long." 

 Diogenes m. (Krauss). 



This species is involved in obscurity at present. Krauss, 

 while adopting the specific name miles, gives a reference, not 

 to Herbst's Cancer miles, but to his Cancer Diogenes. Hender- 

 son, in 1893, Tr. Linn. Soc., vol. v., p. 413, under the species 

 "Diogenes Diogenes (Herbst) " remarks that: " Krauss records 

 the species from Natal, and Eichter records it from Mada- 

 gascar, but their specimens were perhaps referable to some 

 other Diogenes." He adds in a footnote that: " In the British 

 Museum collection there are examples of a large and per- 

 fectly distinct species from Natal." Under "Diogenes miles 

 (Herbst) " Henderson says : " This species lives invariably in 

 shells with a narrow aperture, and its marked peculiarities 

 of form are due to this fact ; at Madras it is nearly always 

 found in Oliva shells." He does not state the size, but gives 

 60 mm. as the total length of the body in a full-grown adult 

 of Diogenes diogenes (Herbst). 



DIOGENES BREVIROSTRIS, Stimpson. 



1858. Diogenes brevirostris, Stimpson, Pr. Ac. Sci. Philad. vol. x., 



pp. 233 (71), 245 (83). 

 Simon's Bay, 21 m. 

 1888. D. b., Henderson, Challenger Anomura, Eeports, vol. xxvii., 



p. 53, pi. 6, fig. 3. 

 Simon's Bay, 18-36 m. 



Henderson says: "This species may eventually prove to 

 be synonymous with Diogenes varians (Costa), as the latter 

 appears to be subject to considerable variation."
