cords. The anal sinus is distinct, the columella convex and with a “V”-shaped groove. 
The colouring is straw, with a large brown blotch on the dorsal side of the body whorl 
(Figs. 3-5). 
Three syntypes of Mitra lachryma Reeve, are in the B.M.(N.H.) No. 1980107. 
The illustrated syntype, length 6.8 mm, width 3.1 mm, is here designated as the 
lectotype. The lectotype has 6 whorls and a worn protoconch, c. 20 axial ribs and 
3-4 spiral striae on the penultimate and 11 axial ribs and 7 grooves + 13 spiral threads 
on body whorl, columella “V”-grooved, dorsal side of body whorl with a spreading 
brown blotch (Figs. 6,7). 
The lectotype of Cythara garrettii Pease, is in the B.M.(N.H.) No. 1962780, 
length 7.8 mm, width 3.4 mm. The lectotype has 6% whorls and a broken protoconch, 
a -grooved columella and a brown blotch on the dorsal side of the body whorl 
(Figs. 8,9). 
The illustrated syntype of Columbella (Seminella) stepheni Melvill & Standen 
(and at the same time the syntype of C. (S.) pacei Melvill & Standen) is in the 
Manchester University Museum No. EE B778, length 4.0 mm, width 1.8 mm. This 
worn syntype, which is here designated as the lectotype, has 5'4 whorls and a worn 
protoconch, 16 axial ribs and 4 spiral striae on the penultimate and 9 axial ribs and 18 
spiral striae on the body whorl (Figs. 10,11). 
The two very worn syntypes of Columbella dibolos Barnard, are in the South 
African Museum No. A29636 according to Kilburn (1986). 
The holotype of Mitrolumna iki Kay, is in the Bernice P. Bishop Museum, 
Honolulu, No. 96824, length 3.5 mm, width 1.5 mm. However, since the holotype was 
unavailable for examination, I examined 2 paratypes in the B.M.(N.H.) No. 1982265 
from the type locality, length of illustrated paratype 3.2 mm (Fig. 12). Paratypes had 
3% whorls of the teleoconch and 4-414 milky-white smooth embryonic whorls, axial 
ribs which are becoming obsolete towards the outer lip on the body whorl, 3 spiral 
cords on the penultimate and 8 on the body whorl followed by 7 oblique cords on the 
siphonal fasciole, columella “V”-grooved, outer lip with blunt denticles posteriorly; 
orange-brown in colour, some nodules at body whorl suture white. 
Kilburn (1986) and Drivas & Jay (1986) discussed Mitromorpha (Anarithma) 
metula (Hinds) from South Africa and Reunion Island. The authors illustrated 
various colour and sculptural variants and remarked on the high variability of the 
species. My own examination of about 60 specimens from localities ranging from New 
Caledonia to the Hawaiian Islands and French Polynesia, confirms the author’s 
findings. Drivas & Jay’s (1986) illustration of the typical metu/a form is actually the 
form stepheni, their iki form is typical metula and their stepheni form is the form 
lachryma. The small form of metula illustrated by Kilburn (1986, figs. 158-160) also 
occurs on Mururoa Atoll, Tuamotu Archipelago (/eg. C.Beslu). 
Drivas & Jay (1986) gave the number of embryonic whorls in metula as 34-44. 
In the 60 specimens of metula examined from Pacific localities the size of specimens 
ranged from 3,.0-8.0 mm and the number of embryonic whorls of the protoconch
