Figures 1-4 - Typhinellus labiatus (Cristofori & Jan, 1832) 
1. Nomenclature. Livomo, Italy, 13.6 mm, (RH). 
2. Syntype of Typhis sowerbii Broderip, 1833, Mediterranean, 24.5 mm, BMNH 197461. 
3-4. Protoconch. SEM J. Cillis, IRSNB, scale bars 1000 pm. 
varices, ending as more or less recurved, short spines on 
varices. There are 6 primary cords (Fig. 1), P1-P6, 
occasionally shallow or almost obsolète in some 
specimens, sometimes with one to three secondary 
cords between P2 and P3 and/or P3 and P4, or P5 and 
P6. 
The protoconch has not yet been examined. The 
protoconch of Mediterranean specimens consists ot 1.5- 
1.75 whorls (Figs 3-4). 
Other specimens of T. labiatus were reported lrom 
the western Atlantic. Gertman (1969: pl. 1, fig 5a-5c) 
illustrated a typical specimen of 17 mm from the 
Leeward lslands, near Nevis and reported the species 
also from Portobelo, Panama, from off Texas and from 
Egmont Key, Florida. Other specimens from the 
western Atlantic are occasionally larger and broader 
(Figs 25-29) but like Gertman (1969: 156), we also feel 
that these différences are within the range of variation 
of T. labiatus. 
A specimen collected in Principe by SG was eating 
a small bivalve. 
Fernandes & Rolân (1993: 38) reported they had 
collected in Sào Tomé a species they recorded as 
Typhis cf clarki Keen & Campbell, 1964. We suspect 
these authors were referring to the species which is the 
basis of this paper as one of the current authors (PR)
