Extract

The absorption spectra of haemoglobins from A. glabratus and P. corneus and from B. (P.) globosus and B. (B.) tropicus angolensis were established. There was no difference between the spectra of snails which transmit Schistosoma mansoni or S. haematobium and the spectra from related insusceptible species.

The snail haemoglobins produced absorption spectra which differed from mammalian pigments only in the position of a single peak.

Snail blood occasionally produced additional small peaks in the ultra-violet region, which may have been due to blood proteins other than the respiratory pigment.
