covering that Stimpson’s genus Monoculodes was evi- 
dently the same as part of the genus Kroyera, Stimp- 
son’s name was adopted for those species which evidently 
belonged to that genus ; whilst that of Kroyera has 
been given to the following species, which could not 
be retained in it. 
Since the above description has been in type, we have 
obtained an animal which coincides with the present 
genus in all its conditions, except that the eyes coalesce 
into a single organ, as in Monoculodes. We think it more 
convenient for the present to retain both in this genus 
until future observation shall enable us to determine the 
relative importance of this distinction.
