12 " ENDEAVOUR " SCIENTIFIC RESULTS. 



Sub-Family PENEROPLIDIN.E. 

 Genus Cornuspira, SchuUze. 

 CoRNUSPiRA carinata, Costa, sp., VAR. EXP ANSA, var. nov. 

 (Plate I., fig. 3.) 



In this variety the tests partake of the characters of both 

 C. carinata, Costa, sp.i and C. foliacea, Philippi, sp.2. The 

 test, although increasing rapidly in width, as in G. foliacea^, 

 is, however, depressed on the sides and even tends to 

 become concave, as in typical examj^les of C. carinata. The 

 larger specimen of the varietal form has a diameter of 

 1.23 mm. 



Forty miles south of Cape Wiles, 100 fathoms. Two 

 examples, identical in varietal form. 



Cornuspira crassisepta, Brady. 



Cornuspira crassisepta, Brady, Chall. Rep., Zool., ix., 1884, 

 p. 202, pi. cxiii., fig. 20. Egger, Abhandl. d. k. 

 Bayer. Akad. Wiss., CI. ii., xviii., 1893, Abth. ii., p. 54, 

 pi. iii., fig. 22. 



This species was first described by Dr. Brady from speci- 

 mens dredged in the Faroe Channel by the " Knight Errant." 

 Since then it has been recorded living off the coast of 

 Australia by Dr. Egger. Latterly the species has occurred 

 fossil in the older Tertiary deposits of Victoria, where large 

 examples are found, usually twice the diameter of the living 

 shells. 



Forty miles south of Cape Wiles, 100 fathoms. One small 

 example, 46 mm. in diameter. 



Cornuspira involvens, Reuss, sp. 



This widely distributed species was also an inhabitant 

 of the early Tertiary seas around the Australian Continent, 

 being found in some abundance in the Victorian Oligocene

3. An abnormal form of Cornuspira foliacea, with a concave and a convex 

 face, has been noted and figured by Heron-Allen and Garland, from shore- 

 sand at Selsey Bill, Sussex, England (See Journ. Roy. Micro. Soc, 1911, 

 p. 305, pi. ix., figs. 5, 6.).
