Organs of vision differing from tlie normal compound eyes of tlie AmpM- 
poda, and consisting only of single or detached lenses. Hands subchelate. 
Whilst accepting the Genus Ampelisca as the type, 
we are obliged to modify the characters of the present 
subfamily from those given in the tc Catalogue of Am phi - 
poda” in the British Museum, as undoubtedly the genus 
Haploops of Liljeborg, with which we have only re- 
cently become acquainted, must be comprehended in it. 
The last-named genus, of which Professor Liljeborg has 
taken two species upon the coast of Norway, and which 
we may anticipate finding upon the northern shores of 
Britain, differs from Ampelisca in the absence of the 
prolonged head, and in only having two instead of four 
simple eyes. 
We would here express our obligations to Professor 
Liljeborg, for his courtesy in sending us a drawing of 
Haploops tubicola.
