GEN. PLANES, Bowdich.

Credit for the name of this genus should, I believe, not be 

 given to Leach, but should be shared between T. E. Bowdich 

 and his widow, Mrs. S. Bowdich, if the signature of the plate 

 on which the Planes is figured refers to the latter. Mr. 

 Bowdich records an incident of his voyage, when two 

 immense logs of American pine were hauled on board. 

 These were completely water-logged, " covered with a con- 

 tinued mass of the lepas anatifera," and "also full of the 

 teredo navalis." Further, " A small crab, fig. 3, a and b [on 

 the plate 2ft, 26] which I conceive to be a new species of 

 planes, was found in great numbers amongst the anatiferce." 

 A footnote adds: " It was of a delicate, but bright, rose colour : 

 from the symmetrical form of its test (notched so regularly 

 as to increase the projection and distinctness of its chaperon), 

 it may be called P. clypeatus." The plate facing p. 16 is 

 signed " S. Bowdich del et litJiog." 



PLANES MINUTUS (Linn.). 



1758. Cancer minutus, Linn., Syst. Nat., ed. 10, vol. i., 



p. 625. 

 1825. Planes clypeatus, Bowdich, Excursions in Madeira, p. 15, 



figs. 2ft, 26. 

 1905. P. minutus, Stebbing, S.A. Crustacea, pt. 3, p. 43. 



Nos. 165, 166, sent by Dr. Gilchrist from False Bay, and 

 No. 15070 by Dr. Peringuey, specimens taken 38 miles N.W. 

 of Table Bay. 



The Nautilograpsus major, M c Leay, Annulosa of S. Africa, p. 66, 

 and N. smithii, M c Leay, on the following page, are probably not 

 distinct from Planes minutus, or at any rate do not seem to have 

 been recognised by subsequent authors. 



GEN. SESAEMA, Say. 



1817. Sesarma, Say, Journ. Ac. Sci. Philad., vol. i., p. 76. 

 1905. S., Stebbing, S.A. Crustacea, pt. 3, p. 44.
