Due to a printer’s error in the article entitled ‘On the respiration of Torpedo marmorata’ by G. M. Hughes which appeared in Volume 73, pp. 85–105, the first line was omitted from the legend to Figure 3. The legend should read as follows:

Fig. 3. (a) Plot showing change in oxygen consumption during period of equilibration in Raia clavata. The dotted line shows the mean level during this time. (b) Oxygen consumption of three specimens of Torpedo marmorata over a period of 2–3 days. Different symbols refer to different individual fish.
