[Gabriel Neve]

Dear Ante,

I generated a pdf of
> Costa, A. 1885. Notizie ed osservazioni sulla geo-fauna Sarda. Memoria
> quarta. Atti Accad. Sci. fis. mat., Napoli. (2a) 1(13): 1-31. [1885.??.??]
>
at biodiversity heritage library.
Please note that parts two (Memoria seconda) and three (memoria terza) 
ara also available in the same volume of
Atti della Reale Accademia delle Scienze Fisiche e Matematiche, Serie 
seconda, vol 1, 1888, in parts 2 and 9

The pdf of part 4 can be downloaded directly from :
http://www.biodiversitylibrary.org/pdf4/063615800182007.pdf

Unfortunately, I could not locate the other reference

published in

which is present at the University of Michigan, but cannot be downloaded 
(at least not from outside the USA)

Best wishes,

Gabriel
