28 ALECTRION. 



A smaller, more gracefully formed shell than the type, and 

 typically sufficiently distinct, but varies much. Kiener's figure 

 is a poor one (fig. 47), and that which Reeve has given, as well 

 as his description, refers to a N. taenia, Gmel. The following 

 are synonyms: N. rufula, Reeve (tig. 48), and N. npirata, A. 

 Ad. (fig. 49). 



Var. SUTURALIS, Lain. Figs. 52-54. 



Shoulder coronated by a row of tubercles. 



Length, 1-1 '5 inches. 



Philippines, Australia, New Caledonia. 



Fig. 54 represents the typical form, whilst iig. 53 shows a. 

 variety with the tubercles almost obsolete, passing into v:ir. 

 elegant . N. intermedia, Dunker (fig. 52) is an equivalent form, 

 and N. bucculenta, Marrat, an unfigured species, may also be 

 placed here. 



N. HIRTA, Kiener. PI. 8, figs. 50. 51, 55-59. 



Light yellowish or orange-brown, with usually a pale central 



band. Length, 1 inch. 



Philippines, Australia, Polynesia, Indian Ocean . 

 The undoubted synonyms of this species are N. VitiensiK, 

 Hombr. et Jaeq. (tig. 57), N. titoliczkana, Nevill (tig. 58), N. 

 costata, A. Ad. (fig. 50) and N. crenulata, Reeve, not Brug. (fig. 

 56). N. crenulata, Brug. is not to be identified positively, but 

 looks more like N.-arcidaria than the present species. N. hirta 

 probably runs into the next species, N. moni/e. N. riodifera, 

 Powis (fig. 55), is not a satisfactorily determined form ; if the 

 figure which I copy from Reeve is correct, it appears to be a 

 very broad, short, large specimen of N. hirta, connecting with 

 N. pulla, Linn. The localities of N. nodifera, " Panama and 

 Galapagos," are almost certainly incorrect. N. bifaria, Baird 

 (fig. 59) is, I think, a stumpy variety. 



N. MONILE, Kiener. PL 9, figs. 60-68. 



Yellowish or ash color, with a rather broad darker central 

 band, and sometimes narrower ones above and below it. Surface 

 beautifully polished, ribs more fiexuous than in .V. hirta; a 

 double row of nodules below the suture, caused by an impressed 

 line on the sloping shoulder. Length, 1 inch. 



Philippines, Australia,, Central Polynesia.
