 broader merus joint to the second maxilliped, in the presence of small exopods

Near S. mollis Smith. Besides differences of minor importance, the follow- 

 ing structural difference is apparent : in S. mollis the posterior pleurobranchia 

 of the antepenultimate thoracic segment is replaced by a small simple lamella, 

 which is concealed beneath the following gill, while in S. inous the said 

 pleurobranchia is well developed and unconcealed.
