closely. But the most interesting thing in the whole 

 Memoir is the description of a new worm, from which it 

 appears that Rolando had already observed Monostomum 

 faba. He found this worm by pairs in tubercles the size 

 of peas, with which the cutis of a Starling was beset all over. 

 The figures which he has given of two of these worms, which 

 he referred to Globular ia, resemble in all respects the 

 drawings published by Creplin in these Archives. (Year 5, 

 Bd. I.) The two intestinal sacculi, the uterus, the oviducts, 

 and the ovaries (dotterstocke) are distinctly recognisable, 

 but it must be confessed that Rolando has himself given an 

 incorrect explanation of them.
