82 STALK-EYED CRUSTACEA. 
for other species by A. Milne Edwards (H/asmonotus brevimanus and Galathodes 
latifrons). For Munidopsis brevimana Hend. may be substituted Mwndopsis 
ciliata, a name lately given by Wood-Mason to a Munidopsis from the Bay of 
Bengal, which does not appear to be distinct from Henderson’s species.* 
Elasmonotus latifrons Hend. may be called Mundopsis latirostris. 
The genus Munidopsis, taken in this extended sense, contains about seventy 
species, 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- 
sidérations Générales sur la Famille des Galathéidés,” + written by Prof. Milne 
Edwards conjointly with Mr. E. L. Bouvier. In this memoir the classification 
of the Galateide 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’. datifrons and G. tridens alone in Galathodes, 
the eight others being transferred to Munidopsis. So of the six species of 
Orophorrhynchus of the original paper three are now transferred to Munidopsis, 
one to Hlasmonotus, one (O. spinosus) is ignored, leaving but one of the origi- 
nal species, O. ates, 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 Bouvier maintain, that the most char- 
acteristic of the species ranged by them in the genera Orophorrhynchus and 
Llasmonolus 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 
structure from Munidopsis, yet form a sharply defined and natural group dis-
