MOLLUKCA — IIKUKHV, 



•291 



iiig a conspicuous protlissocoiich on the summit, situated at a 

 third of the shell's length from the ))osterior end. Hinge plate 

 arclied ; chondrophore projecting, almost symmetrical and per- 

 pendicular, distant from the teetli. On the anterior sid(^ five, on 

 the posterior four, well developed teeth, besides a rudimentary 

 tooth at the conclusion of each series. Apparently a thin 

 amphidetic ligament exists, but I could not assure myself of this 

 feature. Pallial line indistinguishable. Length, 2-5 ; height, 2 ; 

 breadth of single valve, -7 mm. 



Two complete specimens and a few separate valves were taken 

 off Port Kembla in 63-75 fathoms.

I have identified this species by comparison with tlie author's 

 types, kindly lent me by Mr. A. Morton, the Cui^ator of the Tas- 

 manian Museum. The "Thetis" shell here figured is 1 "6 mm. long 

 and 1 "2 high ; whether it is adult or not my series is insuflicient to 

 decide, but I incline to the opinion that it is. Tate and May 

 have united this* with N. antijiodum, Hanley, and N. micans, 

 Angas. As the species 

 of Woods does not agree 

 with the descriptions of 

 Hanley or Angas, or with 

 specimens determined as 

 antvpodum and micans 

 respectively, their con- 

 clusions are not here 

 accepted. 



A few examples which 

 the " Thetis " took came
