Abstract
The absorption spectrum of hemolymph from the mesopelagic mysidacean Gnathophausia ingens indicates the presence of a hemocyanin. Oxygen equilibrium curves of G. ingens hemolymph demonstrate an unusually high affinity for oxygen which may be physiologically significant for this aerobic, permanent resident of the oxygen minimum layer.

## Abstract At concentrations between 0 and 15 mM, Lβlactate increases the oxygen affinity of the hemocyanin in hemolymph dialysates of the crabs __Carcinus means__ and __Cancer pagurus__ without changing the Bohr effect. A possible role of lactate and other anaerobic end products as cofactors regu
## T W O FIGURES That no two hemoglobins are quite the same was pointed out some years ago by Barcroft ('28). New evidence from many sources has confirmed his observations. Furthermore The authors wish to make acknowledgment of facilities made available f o r these studies by the U. S. Bureau of
