Organs of vision differing from the normal compound eyes of the Amphi- 

 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 te Catalogue of Amphi- 

 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.
