ALBERSIA-PANDA. 293 



Diam. maj. 29, min. 24, alt. 10 mill. (Hedley.) 



Geotrochus elisus HEDLEY, Proc. Linn. Soc. N. S. Wales, (2), p. 

 86, t. ll,f. 24, 25. 



The Macleay Museum contains four dead shells of this species, 

 which appear to resemble G. pelechystoma Tapp. Can., purchased 

 from Mr. Goldie, who collected them in British New Guinea. 



Genus? ALBERSIA Mts. 



A. PSEUDOCORASIA Strubell, Nachr.-Bl. D. M. Ges. 1892, p. 47. 

 Unfigured. Halmahera. 



Genus PANDA Albers. (Vol. VI, p. 74). 



Mr. Hedley adopts the following arrangement of species and 

 varieties : 



P. FALCONERI ReCVC. 



Var. maconelli Reeve. (See Manual VI, p. 76). 



Var. azonata Hedley. 



Bandless, entire shell straw-yellow colored. 



Var. tigins Hedley. 



The original dark spiral bands have here become disintegrated into 

 separate blotches, and these latter have further become confluent 

 with those above and beneath, so that the band pattern is changed 

 from regularly spiral to irregularly longitudinal and zig-zag, in 

 which state it approaches the pattern of atomata and larreyi. 



P. ATOMATA Gray. (See Nautilus VI, p. 9, May, 1892.) 



Var. kershawi Brazier. 



In this genus, neither contour nor coloration can be relied upon to 

 furnish specific characters, and I cannot admit Jcershawi Brazier 

 (P. Z. S., 1871, p. 641) as a valid species. No habitat has been 

 recorded for this form between the valleys of the Hunter and of the 

 Snowy River. Yet, despite their geographical isolation, southern 

 specimens can be precisely matched, as Dr. Cox has kindly demon- 

 strated to me, by northern shells. Fossil specimens of this species 

 have been identified by Dr. Cox, from Victoria, but none have 

 come under the writer's observation, nor is he aware of any men- 

 tion of the fact, in the literature of the subject. (Hedley.)
