'ENDEAVOUR" SCIENTIFIC RESULTS. 



seven ribs, these have mostly eight, but sometimes nine or 

 even ten. The intercostal threads are less distinct in the 

 western examples. 



D.— BRACHIOPODA. 



Campages jaffaensis, Blochmann. 

 (Plate XX., figs. 41, 42.) 



Magasella jaffaensis, Blochmann, Trans. Roy. Soc. S. Austr., 

 xxxiv., 1910, p. 92, pi. xxvii., f. 6-9. 



In describing this species. Professor Blochmann seems to 

 have used imperfect material, at any rate, his figure displays 

 the brachial apparatus in a broken state. It is therefore here 

 refigured. 



Ihe original definition of Magasella'^ runs :^ — "Shell with 

 the reflected portions of the apophyses united, forming a 

 loop." In the Australian shell the union of the apophyses is 

 carried to a much greater extent. They join in a hood or 

 funnel rather than a loop. The ascending and descending 

 limbs also coalesce in a fold which forms a double wall to the 

 funnel. Further, the mesial septum does not project beyond 

 the fold and is insignificant compared to the development 

 attained in typical Magasella. 



These characters seem as substantial as those by which 

 Magasella is differentiated from other groups, and I have 

 therefore already employed them to found a genus Campages.^ 

 C. jaffaensis is quite distinct from the type species C. furcifera, 

 which attains a larger size and has the corners of the mouth 

 turned down. F'rom P. Eichler's illustrations'^ it would appear 

 that Magellania joubini, Blochmann, should also be referred 

 to Campages. 



In describing Cistella australis, Blochmann^ appears to have 

 overlooked Dall's correction^ of that generic name. Cistella, 

 Gray, 1853, was preoccupied by Cistella, Gistel, 1848; in sub- 

 stitution, Dr. Dall has proposed "Argyrotheca." 



Hah. — The "Endeavour" trawled C. jaffaensis in 40 

 fathoms north of Cape Borda, South Australia. I have taken 

 it in 250 fathoms outside Sydney, in 80 fathoms outside 

 Narrabeen, and, in conjunction with Mr. W. L. May, in 100 

 fathoms off Cape Pillar, Tasmania.
