4 FULTON : LIST OF SPHOEROSPIRA SECTION OF THERSITES. 



T. lesson i v. lutea, f. ^;ir. 



PI. r, fig. .1. 

 Loc. — N. Queensland. 

 Same form as les^Aoni v. aureedetis/.'^, liut of a light-yellowish colour Of 

 three specimens before me one is entirely bandless, but the other two have 

 the narrow light-brown spiral bands on earlier whorls, the same as one finds 

 on most specimens of aureeiJemix. 



3.— T. eurtisiana, I'n. 

 P.Z.S., T863, p. 528. 

 = hala, Braz. : Proc. Linn. Soc. N.S.W. (iii), 1878, p. 78, pi. 8, fig. 4. 

 Lor. — Townsville and Magnetic Is., Queensland. 

 Somewhat like lf'.<>i07ii in form and coloration, but the whorls increase 

 rather more rapidly in size, it has half a whorl less, the aperture is not 

 quite so broad, the peristome is less dilated at the point of insertion and 

 of a light reddish-brown colour, not white as in /I'.-^son/. 



4.--T. andersoni, Cox. 

 P.Z.S., 187 1, I). 644, pi. 52, fig. 4. 

 Lo''. — Rockhampton, Queensland. 

 Type in British Museum. 

 This species is most variable in size : of the twenty before me the following 

 are the dimensions of four specimens : — 



Alt. 15, maj. diam. 27 millim. 

 Alt. 18, ,, ,. 26 



Alt. 21, „ „ T,^ 



Alt. 26, „ „ 30 

 Some specimens are quite imperforate, but more commonly it is more 

 or less perforate. 



Pilsbry in Tryon's Manual, vol vi, p. 172, pi. 39, figs. 82 and 83, 

 describes and figures perforate specimens of this species as i/u/e/', but gives 

 a figure of the true iju/ei on plate 2t„ figures 65 and 66. 



Andersoni can be separated from incei by its thim er substance, its less 

 oblique, less expanded, and, brown peristome, it is also less openly umbilicated 

 and has half a whorl less, 



From yulei it can be distinguished by its lighter coloration and 

 narrower bands above, its narrower umbilicus and much less expanded 

 peristome. 



5.— T. yulei, Foibss.
