is quite —— Ü Cossmann's choice of Brocchina seems to be the least 
discordant the name Brocchina pukeuriensis (Sut.) may z used till 
some more аш М alternative is found. mete anomala M. & M. from 
Hampden is possibly another congeneric species, while “ Borsonia ” cincta 
(Hutt.) certainly is, and is doubtfully separable specifically. 1% has 
Australian Tertiary forms as Cancellaria ptychotropis Tate and C. gradata 
Tate, which have been variously йа in Bivetia and Aneurystoma, but 
both these бы seem unha ; Plesiocerithium seems nearer, but 
the Neozelanic shell had better remain in Admete until the family is 
ue Bivetia (?) brevirostris (Hutt.) is the New Zealand representative 
С, ci Tate, but the relation is not very close. Admete maorium 
M. is possibly a Sveltella, but may be left in Admete at present. 
Of the thie New Zealand members of this family, nm ambigua 
Hutt. is probably an Actaeon, and A. lacunosa Hutt. a Bonellitia. 
À summary, ive don of the Target Gully members of this family reads,— 
Admete (?) maorium M. & M. 
Admete (?) suteri (M. & M.). 
- Bivetia (?) brevirostris (Hutt.). 
Brocchina pukeuriensis (Sut.). 
The name Siphonalia cannot be retained. Iredale has proposed t 
name Verconella (6a) for the forms with large embryos, strong spira 
sculpture, and generally rounded whorls, while he puts S. nodosa ( esi 
in the subgenus Aethocola. There are many fossil species in our Tertiary 
that must be placed with S. nodosa (Martyn), and in Mr. Marwick's opinion 
A la, which has a deep sinus at the extremity of the anterior canal, 
must be treated as a full genus and removed to the family Buccinidae, while 
Siphonalia (which is a Japanese genus and has no representative in New 
Zealand) and Verconella belong to the family Chrysodomidae. Of the list 
species, S. costata src S. conoidea (Zitt.), and S. nodosa zitteli Sut. belong 
to Aethocola, while S. caudata eda so eset eon at ue NS 
and S. subrefleza (Sow.) fall venie y

ilarly, Sow.) is wrongly recorded, Suter het probably 
mistaken e xamples of one of the Verconella n. spp. mentioned above for 
the South American shell. 
The species of Aethocola are in no better state. Suter’s S. nodosa zitteli 
is well worthy of specific rank, but the Target Gully shells so named are 
very different from both the type from White Cliffs and the described 
specimen from Nelson, which itself is not conspecific with the type. The 
Target Gully shell is a ae 3 and it was also on a variant of this 
that Suter’s record of noidea (Zitt.) was based, so that S, zitteli Sut. 
and S. conoidea (Zitt.) Should disappear from these lists
