In a verbal discourse (November 1872) with the renow- 

 ned Swedish naturalist mr A. W. Malm in Gothemborough, 

 that gentleman told me that he still adhered to his formerly 

 (o. cit.) expressed opinion about the two pretended species » oc- 

 toculata* and »reticulata». 



Obs\ In the 25:th of August 1868 I caught a young in- 

 dividual of Aulastoma sanguisuga w^hich, when I was examining 

 its external shape, disgorged — »per os» — an other leech 

 of almost its own length. This one, a yoimg Nephelis octocu- 

 lata sanguinea, proved itsself to be alive, though^ the forepart 

 of the body — it was been swallowed the fore-body the first 

 — was to such a degree destroyed, that no eyes were to be 

 seen. Yet two days later I still perceived motions in the mu- 

 tilated body.
