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.
