Remarks on Molgula liitkeniana Traustedt. 
By 
Prosper Bovien. 
In his paper „Vestindiske Ascidiæ simplices“ (Vidensk. Medd. 
Naturh. Forening, København, 1882) Traustedt establishes a new 
species of Molgula, M. liitkeniana , but mentions it only quite pas- 
singly in an analytical table of species, giving these characters for

it: The branchial sac has six folds on each side; the dorsal tub- 
ercle is horseshoe-shaped, with the aperture turning backwards; 
the dorsal lamina is toothed; the anal opening has a plain border. 
No further description was ever published by Traustedt, and 
apparently the species has never been found or examined by other 
investigators, so that our knowledge of the species rests alone on 
the short notice in the paper quoted.
