Hah. — The type was found at Glenelg by Master Bragg, 

 and we have pleasure in naming it after him, and at the same 

 time complimenting his father, Prof. Bragg, one of our most 

 honoured Fellows, who has just been distinguished by the 

 Fellowship of the Royal Society of London. 



Mr, Zietz has also taken eight specimens during ten 

 years' collecting on our beaches ; so that it is a rare species 

 here. 



Mr. Hedley says it does not seem to occur on the Pacific 

 coast of Australia, but he has it from Victoria.

Arcularia dipsacoides, Hedley, Records Austr. Miis., vol. vi., 

 part 5, 1907, p. 359, pi. Ixvii., f. 21. Type locality, 800 fathoms 

 35 mile.s E. of Sydney. 



Dredged off Cape Jaffa, in 130 fathoms, 41 examples; in 

 300 fathoms, 10, all dead. 



Two individuals were taken alive in 130 fathoms, off Cape 

 Jaffa, and furnished radulse. They contain about fifty-three 

 rows, and are of the ordinary rachiglossa type. A large 

 lateral with two well-curved simple cusps fold over a rachi- 

 dian tooth with ten cusps, of which the outermost on each side 

 is very small. In one individual, one cusp situated at the 

 centre is the largest and has frequently five cusps on one 

 side and four on the other. In the second individual, the 

 middle two are largest. The rest vary very much in 

 relative length in different rows, so that scarcely any two 

 rachidian teeth exactly correspond. 



Vermicularia flava, n. sp. Fig. 1. 



Shell an ochre-yellow-coloured tube, 

 varying in diameter from 1 to 1'5 mm., 

 moderately thick, coiled in flat discs of 5 

 or 6 mm. in diameter, each formed of three 

 or four spirals; the discs are superimposed 

 to form a cylinder. Section of tube circu- 

 lar. Surface has sinuous growth-lines, 

 Ante-current at the margins of attachment 

 to adjacent coils and at the centre of the 

 free surface, varying in validity, sometimes 

 erected into a collar. The anterior end 

 stands free. 



The type, after forming a flat cylinder 



of two discs, produces two more discs at 



right angles to these, and then has a free 



tube of 7 mm. length. The discs may be formed from the 



centre outwards, or from the circumference inwards. The
