Hapalogaster cavicauda (Stiinps.) =Lomi8 (De H., nec M.-E.), described 
by Boas, 1. c. p. 122, pi. v. figs. 200 a- 6, recapitulated, p. 194. It is, accord-

Mixtopagurus, g. n. Intermediate between Fagurus and Fylocheles. 
Cepbalothorax like that of the former, abdomen crustaceous, formed by

Fylocheles, g. n. Distinct from Fomatocheles (Miers) by the absence

closes the hinder one. Id. ibid. 
Ostraconotus, g. n. Cephalothorax quite coriaceous, short, rounded ; 
abdomen rudimentary, soft, scarcely annulated, appendages of the pen-
