MCERA.

This genus was founded by Dr. Leach to receive 
Montagu’s Cancer ( Gammarus ) grossimanus ; but it was 
ignored by Milne Edwards and most authors, until Dana 
reinstated it ; unfortunately, however (no doubt from 
Leach’s inadequate description), he attributed the cha- 
racter of this genus to Leach’s type of Melita, and on the 
other hand described his genus Melita not in accordance 
with the typical species. 
The vignette represents young naturalists in deep 
research.
