Head gently rounded and blunt in front. Dermal granules vary- 
ing from simple or stellate booklets to blunt, rounded tubercles ; no 
great mass of the latter observed in advance of the head or the 
paired fins. Caudal fin very large. 
Fraas published a very complete description of the fish, to which 
he gave the name of S. acanihoderma, making known the skeleton 
almost in its entirety. We follow von Meyer and Zittel in iden- 
tifying this form with the species previously described by MUnster.
