Bengal, which does not appear to be distinct from Henderson's species* 

 Elasmonotus Mifrons Hend. may be called Munidopsis Mirodris, 



The genus Mimdopm, taken in this extended sense, contains about seventy 

 specles; sixteen of which were discovered during the voyage of the ^^ Alba- 

 tross" in 1891, and were first described in my preliminary report on the 

 Crustacea of the expedition in 1893.

After the present report was written I received a memoir entitled " Con- 

 siderations Generales sur la Famille des Galatheides,"f written bj Prof. Milne 

 Edwards conjointly with Mr. E. L. Bouvier. In this memoir the classification 

 of the Gakdeidcc is treated anew and in more detail. All of the genera pro- 

 posed by the senior author in 1880 are retained, although transformed almost 

 beyond recognition by the imposition of new diagnoses and new limitations. 

 Galathodes is restricted to the species characterized by a broad, flat, triangular 

 rostrum, often carinated on its upper side, and armed towards its anterior end 

 with a pair of prominent lateral spines or teeth, in front of which the distal 

 extremity of the rostrum suddenly contracts. This new diagnosis of the 

 genus Galathodes eliminates eight of the ten species upon which the genus 

 was originally based, leaving G. Mifrons and G. Iridcns alone in Galathodes, 

 the eight others being transferred to Miinidopsis. So of the six species of 

 Orophorrhynchus of the original paper three are now transferred to Munidopsis, 

 one to Elasmonotus, one {0. spmosus) is ignored, leaving but one of the origi- 

 nal species, 0. aries, in Orophorrhynchus, of which genus it becomes the type. 

 The difficulty encountered by Prof Milne Edwards in distributing his 

 own species among his own genera would seem clearly to show the artificial 

 nature of the genera proposed, and amply to vindicate the course of those 

 naturalists who have refused to adopt them. 



It is true, as Milne Edwards and Bouvlcr maintain, that the most char- 

 acteristic of the species ranged by them in the genera Orophorrhynchus and 

 Elasmonotus differ from the more typical species of Munidopsis as, much as or 

 more than the species assigned to the genus Galacantha. But there is this 

 difference : the species of Galacantha, although they differ but slightly in 



Munidopsis
