the family, to describe a species, as to have a kind of horse
known as "horse horse." Crepidula crepidula (Fig. 27) is a similar
instance.

~SUB-EMARGINULA INTERMEDIA~ (Plate IX.).--Fig. 22 (late Parmophorus
intermedia) is a white limpet-like shell, covered with a thin brown
epidermis. It is sometimes 1-1/2 inches long, the animal being like a
large yellow slug.

~SCUTUM AMBIGUUM~ (Plate IX.).--Fig. 23 (late Parmophorus unguis) is a
white shell, covered with a thin brown epidermis, and is sometimes over
2-1/2 inches long. The animal is like a big black slug, and, in
comparison with the size of the slug, the shell is very small. A slug
the size of a man's fist would have a shell about an inch long. Most
shell-hunters would pass by a Scutum abiguum, not thinking it had a
shell embedded in its folds. The shell is found amongst rocks in
sheltered places on ocean beaches.

~SIPHONARIA OBLIQUATA~ (Plate IX.).--Fig. 24 is like a brown limpet, about
one and three-quarter inches long. On the right side is the siphonal
groove, which is much more clearly defined in the Siphonaria australis
(Fig. 25). The shell is found in Dunedin.

~SIPHONARIA AUSTRALIS~ (Plate IX.).--Fig. 25 is a brown or
chestnut-coloured limpet, up to one inch in length. The siphonal groove
can be seen on the upper side of the figure. The best specimens I have
found were on the piles of Tauranga Wharf.

~EMARGINULA STRIATULA~ (Plate IX.).--Fig. 26 is a whitish limpet, about an
inch in length. The notch, or fissure, which is a peculiar feature of
this shell, is seen on the end of the shell facing the Lima zelandica
(Fig. 21).

~CREPIDULA UNGUIFORMIS~ (Plate IX.).--Fig. 27 is a parasite shell, over an
inch long, and found inside the lips of other shells. It is a thin,
clear white shell, and is well named, from unguis, a finger-nail, which
it much resembles. It varies in shape from nearly flat to semi-circular,
according to the curve of the part of the shell on which it grows. The
Crepidula shells are easily identified by the shelly internal appendage,
or lamina, in which the body of the animal rests. From the peculiar
effect of this lamina the Crepidula shell looks like a boat. This shell
has recently been renamed Crepidula crepidula, a silly duplication, like
Lima lima (Fig. 21). The Maori name for the Crepidula is the same as for
a limpet, namely, Ngakahi or Ngakihi.

~CREPIDULA ACULEATA~ (Plate IX.).--Fig. 28 (late Crepidula costata) is an
oval-shape
