58 CRUSTACF.ANS OF THE 



from the Coast of Mozambique that in 1878 were described 

 by the former under the name of Menippe Fornasinii^ and 

 Dr. Romer thereupon informed me that it was iden- 

 tical with them. I therefore conclude that Bianconi's 

 species and Myomenippe Leguillouii A. M. E. are indeed 

 one and the same species. 



Galene'^ Jiirtipes Jacq. and Lucas and Myom. Leguillouii 

 A. M. E. are apparently ideutical, as both the description 

 and the figures in the » Voyage au Pole Sud" fully agree 

 with the type specimens of the latter. 



Ortmann refers to this species also Haswell's Para- 

 ruppellia saxicola from the Eastern coast of Australia, 

 which indeed appears quite probable. As also a specimen 

 of Myom. granulosa A. M. E. from the Mergui-collection 

 is lying before me, it will be easy to indicate the prin- 

 cipal differences between the two species of Myomenippe. 



As regards their outer appearance, the general shape 

 of cephalothorax and legs, both species closely resemble 

 one another. The front and the orbits show the same 

 characters, fully agreeing in the number and the form of 

 the teeth. Behind the outer angles of the orbits that are 

 acute and dentiform , in both specimens four teeth are 

 observed and in both the second is the largest of all. 

 This second tooth, however, appears in M. Fornasinii 

 slightly longer in proportion to the first than 

 in Myom. granulosa A. M. E. In M. granulosa A. M. E. 

 the distances between the tip of the second tooth and those 

 of the third and first are about in proportion as 3:2, but 

 in Bianconi's species as 5:3. The first and the second 

 tooth are moreover less prominent in M. Fornasinii., 

 the second tooth indeed is 8-times as long as high, but in 

 Myom. granulosa 6 times: in other words the anterior 

 margin of these teeth appears somewhat shorter in 

 proportion to their length than in Myom. granulosa A. 

 M. E. The margins of the autero-lateral teeth are finely 

 granulate in M. Fornasinii, but in the other the granules 

 are conical, more prominent and less numerous. The inter-
