The record of which this is a continuation was published in tlie 

 Proceedings of the Zoological Society about fourteen years ago. 

 In the interval Mr. Vallentin has continued his reseai'ches dining 

 more or less prolonged visits to the Falklands, with the result 

 tbat very extensive additions have been made to the sei'ies of 

 specimens left undescribed in my earlier report. 



Wlien Samuel Jobnson, in 1771, publisbed his entertaining 

 but politically-ndnded history of the Falkland Islands, there was 

 natundly no forecast in it that the restless " barren ocean " wdiicb 

 breaks on the shoi'es of those wind-swept outposts of civilization 

 would eventually become a happy hunting-ground for students 

 of marine zoology. Nevertheless, as explained in my former 

 paper, the nineteenth century fovind tbose waters fruitful in 

 interest. In the pre.'^ent century, while Mr. Vallentin has been 

 waiting with friendliest patience for my further account of his 

 unwearied and still unexhausted researches, the rush to the 

 Antarctic has incidentally brought the island fauna into renewed 

 prominence. As the following discussion will show, it has 

 engaged the attention of numerous eminent (larcinolog'sts, 

 such as Chilton, Hansen, Ohlin, Ortmann, Thomas Scott, 

 Tattersall, and Thiele. The present paper pi'oposes one new 

 generic name and five new species t ; but Mr. Vallentin's collection 

 has made possible a reconsideration of various forms already 

 known by name, though veiy imperfectly known by nature, If 

 some usefid light has been thrown xipon the.se obscui-ities, it may 

 perhaps be welcomed as compensation for slioi-tness in the list of 

 novelties, at an epoch when the discovery and display of new 

 species has been almost overwhelunngly rapid.

t [The complete account of the five new sjjecies dcscribeil in this roniinunic.irion 

 appeal's here, hut since the names and iireliniiiiavy diagnoses were ])ublished in the 

 "Abstract" No. 132, 1914, these species are distinguished by the names being 

 underlined. — Editor.]
