Reference is made to Krøyer's description of the hermit crab, Pagurus pubescens, and to Stimpson's later description of P. krøyeri. Comparison of specimens of krøyeri with the type specimen of pubescens showed them to be identical. The American species thought by Stimpson to be pubescens and, therefore, left without a name, is now given a name, P. arcuatus. Both species are compared with P. trigonocheirus, and a new diagnostic character, the shape of the anterior division of the third sternite, is used.
