390 DR MITKEAY ON THE DEEP AND SHALLOW-WATER MARINE FAUNA 



Six of the abo^'e species are jjreceded by u mark of interrogation : — Fliakellia 

 ventilabrwn, Salenia hastigera, and Cytheropteron fenestratum have been recorded 

 only from de25ths over 100 fathoms, and might, therefore, not merit the title of shallow- 

 water species ; Parapagurus ahyssorum is said to have been dredged from a depth of 45 

 fathoms in Magellan Strait, but the author of the Challenger Report on the Anomura 

 regards this as an error, as he thinks a shallow-water habitat for the species is quite 

 out of the question ; the two species of Polyzoa (BiceUaria navicularis and Kine- 

 toskias pocillum) are recorded from the coast of Brazil, " 32 to 400 fathoms," so that 

 it is doubtful whether they actually came from less than 150 fathoms.

LIST 11;/. 



In List II. those species apparently limited to the Southern Hemisphere south of the 

 tropic of Capricorn are distinguished by an asterisk. A few of these species were, 

 however, obtained in depths less than 1000 fathoms in the Southern Hemisphere, as well 

 as in depths over 1000 fathoms among the twenty-nine Stations under consideration. 

 We give here a list of 16 such species, with an indication of the localities in which 

 each species occurred in depths less than 1000 fathoms.

species, require verification].
