1 88 The Naturalist of Cumbrae 



of the famous marine biological station at Naples, 

 being anxious to study the embryology of the 

 cumacea, visited Scotland for that purpose in 1867. 

 In his " Investigations of the Structure and Develop- 

 ment of the Arthropoda," he says : 



" Following the friendly advice of Dr. Baird, of the 

 British Museum, I went to Millport, the watering-

 Clyde, on the west coast of Scotland, near Glasgow. 



" Dr. Young, Professor of Natural History at 

 Glasgow University, obliged me by his friendly 

 introduction to Mr. Robertson, the zoologist, well 

 known for his indefatigable faunistic researches. To 

 my great delight Mr. Robertson, at my first visit, 

 showed me a number of species of Cuma, all of which 

 he had captured at Millport He assured me at the 

 same time that I could capture them myself in 

 quantities, and that most of the females would just 

 now be having ova. This was in fact the case." 



Elsewhere he speaks of the discoveries which he 

 had been able to make through " the favourable 

 circumstance that in Millport I met with one of the 

 best known crustacean faunas, and in my honoured 

 friend Robertson obtained the assistance of an 

 exceptionally zealous and well-informed Crustace- 

 ologist" 



In regard to the localities in which the creatures 

 are found, he says, "Very curious is the remarkable 

 delimitation of the species each in its several habitat : 

 Mr. Robertson had already observed the following 

 details years ago, and I had abundant opportunity 

 to convince myself of the complete correctness of
