It is our opinion that Latmatophilus tuber culatus, of 
Bruzelius, may be the female of a species of this genus 
in which the penultimate pair of caudal appendages have 
been broken off and are undergoing the process of repro- 
duction. This suggestion is, indeed, founded only upon 
negative evidence; moreover, we think that we should 
be doing the author of the “ Skandinaviens Amphipoda 
Gammaridea ” injustice, in the present state of our in- 
formation, if we were to insert his genus Lcetmatophilus as 
a synonym of Cyrtophium of Dana, although we anticipate 
that they will ultimately be proved to be the same.
