Figure 30. Specimens of Janthina globosa (Swainson). (A-B) GNS RM5222, Waipu Cove, Northland, New Zealand, SEM; apical views 
of shell (A) and protoconch (B), showing smooth teleoconch surface, and protoconch inclined only weakly. (C-E) Monterosato’s type 
material, photos sent by M. Appolloni (MCZR) and M. Oliverio (University of Rome 1 “La Sapienza”); C, E, MCZR23423/1, lectotype 
designated here of Janthina splendens Monterosato; Alexandria, Egypt; D, MCZR23414/1, lectotype designated here of Amethistina laeta 
Monterosato; Algeria. (F-G) ZMB41985a, lectotype designated here of Janthina patula Philippi, 1844, from Naples, Italy; photos sent 
by C. Zorn (ZMB). Scale bars: A, 3 mm; B, 200 pm; C-G, 10 mm (longer bar applies to C-E, shorter bar to F-G). 
of the syntypes were illustrated by Yen (1942: 219, pi. 20, 
fig. 123,2 images). The larger of the syntypes illustrated by 
Yen (1942: pi. 20, fig. 123, right image), NHMUK1976168a, 
is here designated the neotype of both Janthina globosa 
Swainson, 1822 (Jan) and Janthina prolongata Blainville, 
1822 (Aug). 
Janthina nitens , no type material present in any museums 
the writer has consulted. Menke did not know the locality of 
his specimen. R. Janssen (SMF pers. comm. 18 Aug 2015) 
confirmed that no type material of J. nitens is present in 
the remnants of Menke’s collection in SMF. Therefore, the 
neotype of J. globosa and J. prolongata designated above, 
NHMIJK1976168a, is here also designated the neotype of 
Janthina nitens Menke, 1828. DrK. Schniebs (Senckenberg 
Naturhistorische Sammlung Dresden, pers. comm. 23 Feb 
2016) reported that all material of Janthina in Anton’s 
collection was lost in or after the end of world war two, so 
no type material remains for J. rosea. Therefore, the neotype 
of J. globosa , J. prolongata and J. nitens designated above, 
NHMUK1976168a, is here also designated the neotype of 
Janthina rosea Anton, 1838. The remaining two syntypes 
of Janthina patula Philippi, ZMB41985 (photographs sent 
by C. Zorn, ZMB pers. comm. 30 Jan 2016; Figs 30F-G) 
are labelled “Neapel” (Naples). This name previously was 
assumed to be a synonym of J. pallida , but the deep sinus 
in the outer lip and the protruding, pointed anterior end of 
the columella demonstrate that the illustrated syntype is a 
tall, narrow specimen of J. globosa rather than of J. pallida. 
As the writer has seen only the illustrated photographs 
(Figs 30F-G), the illustrated syntype ZMB41985a is here 
designated the lectotype of Janthina patula Philippi, 1844, 
in case the remaining paralectotype is not conspecific. 
Type material of Carpenter’s (1857) Janthina species 
was not included in Carpenter’s illustrations of the Mazatlan 
fauna (Brann, 1966: 14). However, that is not surprising 
because, as Keen (1968) pointed out, Carpenter illustrated
