68 NEW SPECIES OF TASMANIaN MOLLUSCA, ETC. 



■western side of Frederick Henry Baj^, in a rather exposC'd 

 situation, a short, thick-set banded form is plentiful. On 

 December loth of last year, I noticed they v/ere spawning 

 under fairly large stones. The egg capsules formed dens© 

 masses, closely clustered together. The method adopted is 

 for single capsules to be firmly attached at some distance 

 apart; then three or four others a.re fastened tO' the upper 

 edges of these, giving the combination somewhat the ap- 

 pearance of the growth of the prickly pear. The colour is 

 ivory-white, the stalks whiter. I present drawings, which 

 will give a better idea of the form than much descrip- 

 tion. The height of the single specimen is about 9 mm., 

 that of the cluster about 15 mm. 



PI. XVII., figs. 28, 28a. 



I can also add to our list the following seven suecies 

 and one variety already described by various authors. 



1. Area metella, Hedley, P.L. Soc. N.S. Wales, 1917, p. 



681, PI. li., f. 36-37. About a dozen single valves 

 taken in 100 fathoms off Cape Pillar, and a few 

 from other places on our East and South Coasts, 

 from 10 fathoms downwards. 



2. Pseudarcopagia botanica, Hedley, Roy. S. N.S. Wales, 



1918, Supp. p. 27. This species seems confined to 

 our Eastern and Southern Coasts, where it takes 

 the place of P. victorice, Gatliff and Gabriel, which 

 is found in Basg Straits, and perhaps does not occur 

 South East of the Furneaux Group, where, I found 

 it in profusion. 



3. Zalapais lissa, Suter, Cycloatreina, P. Mall. Soc, viii., 



p. 25, pi. ii., f. 10-11. A number of examples 

 taken in Frederick Henry Bay from kelp roots. 



4. Triphora 'inamillata, Verco ; T. alhovittata, Hedley, var. 



mamillata, Verco, T.R.' Soc. S.A., 1909, p. 285. I 

 recorded this in these proceedings for 1910, p. 309, 

 as alhovittata, but our shells are Verco's variety, 

 which I consider is quite suificiently distinct to be 

 given specific rank. It has also been taken in 40 

 fathoms off Thouin Bay. 



5. Turritella atkinsoni, Tat© and May, var. medioanguJata, 



Verco, op. cit., 1910, p. 125, pi. xxx., fs. 8-9. 

 Several from 50 fathoms North of Maria Island.
