Ponta do Norte; also seen from Ponta do Castelo. The writer 
has seen no material from Pinheiros or from Feiteirinhas 
(currently known as Ponta das Salinas). Janthina typica 
also has been recorded recently from La Esfinge, on La 
Isleta, north-eastern Gran Canaria, Canary Islands, with 
photographs confirming the identification (Meco et al ., 
2015: 61, fig. Appendix 5A; six examined specimens listed 
above). Janthina typica is also recorded from Selvagem 
Grande Island, north of the Canary Islands (Gagel, 1911; 
Joksimowitsch, 1911) and from Sao Vicente on the north 
coast of Madeira (Mayer, 1864a, b;Krejci-Grafe?a/., 1958: 
336). However, the stratigraphy and age at these sites has not 
been described in modern times and these records possibly 
refer to J. chavani. The type material of Acrybia chonberti , 
from a well a short distance east of Casablanca, Morocco, 
is the sole record from another eastern Atlantic locality. 
The holotype of Eunaticina abyssalis (Simone, 2014: 586) 
is a specimen of J. typica found in situ in rock dredged in 
1500-1575 m off Espiritu Santo State, Brazil, SW Atlantic, 
in a case remarkably parallel to that of the earlier-described 
species Kaneconcha knorri (see below under J. chavani). In 
Japan, Janthina typica is recorded from relatively few late 
Miocene-Pliocene (Messinian-early Piacenzian) localities 
along the Pacific coast of Honshu, Shikoku and Kyushu 
Islands. In Australia, Janthina typica is uncommon and 
occurs at one locality in Jemmys Point Formation near Lakes 
Entrance in eastern Victoria, in Grange Burn Formation at 
Muddy Creek, western Victoria, possibly in the unnamed 
early Pliocene limestone overlying Kingscote Limestone on 
Kangaroo Island, and a single specimen is recorded from the 
lower part of Hallett Cove Sandstone on the coast southwest 
of Adelaide. In New Zealand, it occurs rarely in Messinian 
(Kapitean) rocks along the coast between East Cape and 
Te Araroa and in the Gisborne district, the northernmost 
locations where latest Miocene rocks are recorded in New 
Zealand. It also is moderately common at Kaawa Creek, 
SW Auckland and at Cape Kidnappers, Hawke’s Bay (both 
Opoitian, Zanclean), and occurs widely but uncommonly 
in Zanclean rocks in N Hawke’s Bay (22 localities) and 
Westland (10 localities). Schofield (1958: 252), based on 
identifications by C. A. Fleming, also recorded a specimen 
of “Hartungia postulata Bart.” from GS3611, R12/f7541, 
bank near Glasson’s Creek, north of the Waiuku-Runciman 
main highway, Auckland, in a re-collection of GS3611, 
originally listed by Marwick (1948: 8). Localities in 
northern Hawke’s Bay were listed (in part) by Marwick 
(1965: table 4) and mapped (by GNS collection numbers) 
on the geological map in Marwick (1965), although the 
sole discussion in the text (Marwick, 1965: 10) incorrectly 
referred to “ Hartungia postulata ” as one of the species 
first appearing in the Opoitian Stage. Whitten (1973) also 
recorded Waipipian specimens from South Taranaki between 
Inaha Stream and Hawera, not seen, in AUGD. Whitten 
(1973) described 23 new members of Tangahoe Formation, 
but recorded Janthina typica (as Hartungia postulata ) from 
three members only: Whareroa Shellbed (one locality, Q21/ 
f6639), Ohawe Sandstone (three localities, Q21/f6553, 
f6627, f6631, plus an earlier record from Hawera: Laws 
1940b), and Waingongoro Member (five localities, Q21/ 
f6613, f6615-f6618). These localities are listed by Whitten 
(1973, Appendix I) as: Waingongoro Member: Q21/f6613, 
grid reference Q21/108792,150 m E of Inaha Stream mouth; 
Q21/f6615, grid ref. Q21/109792,175 m E of Inaha Stream 
mouth; Q21/f5616, grid ref. Q21/109792, between the 
two previous localities; Q21/f6617, grid ref. Q21/111792, 
325-375 m E of Inaha Stream mouth; Q21/f6618, grid 
ref. Q21/112792, 450 m E of Inaha Stream mouth; Ohawe 
Sandstone: Q21/f6553, grid ref. Q21/134789, SE end of 
Ohawe Beach; Q21/f6627, grid ref. Q21/156776, mouth of 
small stream 1.1 kmNW ofWaihi Beach; Q21/f6631, grid 
ref. Q21/167768, mouth ofWaihi Stream; Q21/f6639, grid 
ref. Q21/214746, Whareroa Shellbed, 250^150 m NW of 
small stream near Hawera rifle range. So in Waipipian (early 
Piacenzian) rocks it occurs in S Auckland (three localities), 
N Hawke’s Bay (nine localities), the Whanganui-S Taranaki 
coast (11 localities), the Kaniere-Arahura district, Westland 
(three localities) and the Chatham Islands (one locality, on 
NW Pitt Island). These widely separated Atlantic, Japanese, 
Australian and New Zealand localities indicate that J. typica 
had a cosmopolitan distribution in tropical and temperate 
seas, just as living Janthina species do.
