Abstract
DE GRAAF1 has recently described a specimen of Xenopus lævis Daudin completely lacking hæmoglobin. Another specimen showing a similar condition was found in a practical class in this Department on September 20. The individual was a male measuring 6.5 cm. from the tip of the snout to the vent. Unfortunately it had been partly dissected under tap water and then left for some hours before my attention was directed to the specimen. It was one of a batch of toads delivered from the Trout Hatcheries near Kingwilliamstown in the Eastern Cape Province and had been in the laboratory for only five days before dissection.
