GAMMARIDjE. 



In some specimens of the young animals, when just 

 enabled to quit the parent, we have observed that the 

 superior antennae are furnished with a secondary appen- 

 dage, formed of a single articulus. 



This species is rather plentifully distributed ; we have 

 received specimens from the Moray Frith, sent us by 

 Mr. Edward and Mr. Gregor. The late Dr. G. John- 

 ston took it in Berwick Bay. Professor Kinahan has 

 taken it in from fifteen to thirty fathoms, on the Scollop 

 Bank, in Dublin Bay. Mr. Webster has dredged it at 

 Falmouth ; and Mr. Jeffreys and the Rev. A. M. Norman 

 have found it in from seventy to eighty fathoms, sixty 

 miles east of the Shetland Islands. 



The following vignette represents the Drogns, from a 

 sketch by Dr. Scott, of Melby, staff-surgeon, R.N.
