PELAGIC LIFE, FALMOUTH. 325 



the contents of a jar containing a tow-net gathering in the 

 vessel containing the gonozooids, and soon observed that they 

 eagerly seized the copepods. By these means I managed to keep 

 them in a healthy condition, and under constant observation till 

 the 15th of October following. During this long time the only 

 important changes observed was a shrinking of the walls of the 

 nectocalyx, and a thickening of the manubrium. Cold weather 

 setting in at this time killed my specimens and stopped my 

 observations. It is curious to note that in spite of all my 

 attempts, I was unable to find attached to the stones where the 

 gonozooids occurred a single specimen of Oladonema radiatum 

 the adult animal of this larval form, which 1 feel sure must have 

 occurred in some abundance near that locality. 



Mammalia. 



On Sunday afternoon the 11th of October, 1891, a fine 

 specimen of Delphinus delphis, about six feet long, was 

 washed ashore in a dying condition near the Falmouth hotel. 

 The unfortunate quadruped as it lay stranded on the shore soon 

 attracted attention, and in a short time was surrounded by a 

 small crowd, who attacking it with knives and sticks soon 

 reduced an interesting specimen to a nearly shapless mass. My 

 friend, Mr. J. B. Tilly, who happened to pass the spot shortly 

 after the occurrence, picked up a single foetus, which he kindly 

 gave to me on the following morning. On measuring this foetus 

 I found it 13-8 cm. in length and 3 cm. in great diameter. On 

 further examination I found it had been subjected to the 

 roughest treatment. The brain was completely gone, the 

 hyoid and sternum considerably damaged. In spite however of 

 these drawbacks, I was able to make a fair dissection of this 

 foetus, and to make out some points of extreme interest to me.
