There can be no doubt that the species commonly known as parvi- 

 cirra is in reality the same as the previously described rotalaria. 

 The only recognized difference between the two is the possession by 

 the latter of distichal series of 2 followed by palmar series of 

 4 (3 + 4). while in the former all the division series are 4 (34-4); 

 but both Carpenter and Hartlaub, who have each treated of the 

 species "parvicirra" at considerable length, admits the more or less 

 common occurrence of distichal series of 2 in specimens they un- 

 hesitatingly refer to it. Dr. Hartlaub, under his "Type B" of parvi- 

 cirra. says that this type has distichal series of 2. and 4 (3-)- 4),
