As the Scotia was engaged in marine research throughout the whole of its long 

 voyage out and home, it was only to be expected that Antarctic specimens would 

 form but a small fraction of the result. In like manner, as several of the halting- 

 places, such as the Cape of Good Hope and the Falkland Islands, had been visited 

 by many keen naturalists on earlier occasions, it was quite likely that species of the 

 group with which this report is concerned would have been in numerous instances 

 already observed. Accordingly, out of some fifty species here discriminated, only 

 six claim to be new, and not more than ten can be regarded as Antarctic or sub- 

 Antarctic in their place of capture. In the vast extension, however, which marine 

 zoology has for some time past been receiving, some retardation in the stream of 

 discovery may not be unwelcome to the systematist. Familiar forms which would 

 otherwise amply repay a thorough reinvestigation are apt to be thrust on one side, 

 when striking novelties are for ever appealing to be introduced. This expedition, 

 like others before it, affords fair evidence that the Macrura are both abundant and 

 varied in great depths of the ocean. But only too often the frailty of their fabric 

 leaves them in a tantalisingly mutilated condition when they reach the surface.
