316 ASELLIDA. 
We have been under the necessity of sinking the 
genus Jeridina of Milne Edwards since our discovery 
that the “absence de la grande lame operculaire,”’ which 
in Jera ‘“‘remplace les premiéres fausses pates,” is a 
sexual character. The type J. Nordmanni of Rathke 
must, moreover, be removed from Janira, to which genus 
it was referred by the last-named author, as it wants the 
long styliform processes at the end of the tail. 
The following vignette of Brighton Fishermen was 
kindly done for this work by Mr. Jennings.
