KEPOKT ON THE GASTEKOPODA. 141 



I am indebted to Dr Gwyn Jeffreys for calling my attention to the spiral strise on this species. 

 I had described the shell originally on a dull day, when these strias were invisible. In a good light 

 they are obvious. Dr Jeffreys refers to the species as a fossil found by the Marquis of Monterosato 

 in the Pliocene of Ficarazzi, near Palermo ; but I am unable to recognise the species in the 

 Marquis's list.

Scalaria funiculata, Watson, Prelim. Keport, pt. 15, Journ. Linn. Soc. Lond., vol. xvL p. 609. 



Station 122. September 10, 1873. Lat. 9° 5' S., long. 34° 50' W. Off Pernambuco. 

 350 fathoms. Eed mud. 



Shell. — Small, rather stumpy, with strongish piuched-out ribs, and compact crimped 

 spirals ; the base is broad, flat, and encircled with a strong spiral thread. Sculpture : 

 Longitudinals — on the last whorl there are about 10, on the earlier whorls 11 or 12 

 strongish ribs, which have broad bases and narrow crests ; they run very straight down 

 the spire, but have each a minute twist to the right at the top, and almost inappreciably 

 to the left at the bottom of the whorls ; they do not extend to the base. Spirals — the 

 whole surface is covered with small, flattened, close-set threads, only separated by ex- 

 tremely minute scratches ; these threads are finely crimped, which gives them the rope- 

 like appearance under the microscope from which the name of the species is derived. 

 Colour darkish. Spire high, conical, with a broadish base. Apex broken. Whorls — 8 

 to 9 remain ; they are regularly convex ; the last is broadish, short, with a broad square 

 flat base defined by a strongish thread round the outside. Suture narrow, impressed, 

 rather oblique. Mouth perfectly round. Outer lip prominent beyond the last rib, rounded, 

 blunt. Inner lip very short on the body, which it crosses with a small shelf, of which 

 there are traces all round the mouth within the outer edge. H. - 23 in. B. - 085. Pen- 

 ultimate whorl, height 0'037. Mouth, height 0*04, breadth 0-04. 



I have an unpublished Scalaria of my own dredging at Madeira, which extremely resembles this 

 species, but is distinct. It is narrower, the crimping of the spirals is finer, the longitudinal ribs 

 extend to the base, which is rounded, and has the basal thread much more within the contraction of 

 the basal rounding than is the case here. 



It is obvious that there is a close connection between this species and the Scalaria longissima, 

 Seg., an undescribed species figured by Dr Gwyn Jeffreys in the Proc. Zool. Soc. Lond., 1884 (p. 

 132), pi. x. fig. 3, and of both with Turbo torulosus, Brocchi, Conch. Top. Subapp., 2d ed., vol. ii. p. 

 163, pi. vii. fig. 4 ; but I am not acquainted with either of these species and cannot compare them ; 

 judging by the figures, however, they are not the same.
