infra angulnm leviter couvexl ; anfractus ultimus spirara fere a:iqiians 

 baud costatus, liris spiralibus numcrosis per-iuconspicuis sculptus, 

 basim versus attenuatus, levissime coustrietus ; apertura oblonga ; 

 columeUa recta; bTbrum teuue, postice breviter siuiiatuiu. Long. 8-50, 

 (liam. 3 mm. 



Hdh.—iit. Yincent's Gulf. 



A white sbell, resembling in form tlie typical ribbed MangUice, but 

 the ribs are only faintly discernible on tbe spire, and obsolete on tbe 

 body-wliorl. 



32. Mangilia alticostata, n.sp. PI. Ill, Fig. 16. 



Testa elongate -turrita, bexagonalis, sordide albida ; spira per- 

 elongata, ad apicem acuta ; anfractus 8, planulati, spiraliter striati, 

 costis longitudinalibus 6, elevatis, acutissimis, continuis instructi ; 

 anfractus ultimus brevis, basim versus constrictus, obtuse angulatus, 

 brevissime rostratus ; apertura oblonga, breviuscula ; labrum acutum, 

 sinu postico latiusculo. Long. 13, diam. 4 mm. 



Eah.—^i. Vincent's Gulf. 



Shell like an exaggerated form of M. IwxagonaUs, Reeve, with longer 

 spire, and ribs more prominent and acutely angular. 



33. Mangilia cuspis, n.sp. PI. Ill, Fig. 17. 



Testa fusiformis, utrimque acuminata, albida, antice fusco late 

 zonata, ad apicem f usca ; spira acute turrita ; anfractus 8, primi 3 

 (apicales) minuti, politi, ca3teri obtuse angulati, spiraliter dense 

 lirati, costis numerosis, angularibus instructi; anfractus ultimus supra 

 angulum leviter concavus, intra convexiuscidus, basim versus attenu- 

 atus ; columella levissime contorta ; apertura elongata ; labrum tenue, 

 postice brevissime sinuatum. Long. 8'50, diam. 3 mm. 



mb.—^t. Yincent's Gulf. 



Allied to M. connedens, with finer sculpture, and distinguished by 

 its sharp brown apex and the brown lower half of the body-whorl. 



34. Mangilia anomala, Angas, (Purpura) Proc. Zool. Soc. 1877, 

 pi. V, fig. 1. This certainly belongs to the Pleurotomidije, and was, in 

 my opinion, correctly placed by Professor Tate in the genus Ifaixjilia 

 (Proc. Linn. Soc. New South Wales, vol. v, p. 131), although 

 Mr. Tryon thought well to replace it in the family Purpurida3. 



3o. Mangilia Australis, Adams and Angas, {Bela) Proc. Zool. Soc. 

 1863, p. 420; and var. mitralis^Bela mitralis, Adams and Angas, 

 loc. cit. I cannot admit this last to be a species distinct from 

 M. Australis, the only difference being a greater length of spine. 

 This species was certainly misplaced in the genus Bela, which forms 

 a characteristic group inhabiting the northern seas. 



36. MiTROMOEPHA Brazieri, Smith, Proc. Zool. Soc. 1891, p. 487, 

 pi. ii, fig. 1. Small imperfect specimens from St. Yincent's Gulf. 



37. Cythara compta, Adams and Angas, Proc. Zool. Soc. 1863, 

 p. 419, pi. xxxvii, fig. 5. Mr. Tryon places this in the genus 

 Baphnella, but, although on the confines, I think it a Cythara. In 

 adult specimens there is a somewhat faint varix behind the lip, which 

 is slightly denticulate within.
