14 LITTORINID^. 



It is the R. Beanii of Hanley. R. teoctilis of Philippi 

 is probably the immature state. Adams's Turbo reticu- 

 latus (" T. quatuor anfractibus reticularis, apertura sub- 

 rotunda. Obs. color albus.") appears to have been the 

 young of R. striata ; but that of Montagu is unquestion- 

 ably the one now under consideration. R. reticulata of 

 Philippi, a Sicilian fossil, is very different. Turton, 

 in his ' Conchological Dictionary/ interchanged the 

 characters of the present species and R. punctura, and 

 reversed the admeasurements.

R. cimicoides, Forb. in Rep. Br. Assoc, for 1843, p. 189. R. sculpta, F. 

 & H. iii. p. 88, pi. lxxx. f. 5, 6. 



Body milk-white and almost transparent : snout short, bifid, 

 of a brownish hue : tentacles slender, with blunt tips : eyes 

 small : foot broad, squarish in front, and pointed behind. 



Shell conic-oval, solid, opaque, somewhat glossy : sculpture, 

 several stout and slightly curved longitudinal ribs, not extending 

 to the base, and crossed by more regular and thread-like spiral 

 striae or riblets, which cover the surface of the last four whorls ; 

 small tubercles or nodules are formed at the points of inter- 

 section ; there are 4 rows of spiral striae on the penultimate 

 whorl ; labial rib thick (sometimes double), traversed by the 

 spiral striae, and marked with minute and numerous hues of 

 growth; top whorls encircled with close- set and punctured 

 striae : colour pale yellowish-white, more or less deeply tinged 

 with reddish-brown, and having usually an imperfect streak of 

 the latter colour close to the labial rib on the outside, which, 

 terminates at the periphery in a broad mark, covering three of 

 the spiral striae ; these markings appear to result from two 

 obscure bands, one below the suture and the other round the 

 base ; apex light orange : spire sharp-pointed : whorls 6-7, 

 sloping upwards, compressed, somewhat gradually enlarging, 

 the last occupying about three-fifths of the spire : suture slight, 

 but distinctly channelled : mouth more round than oval, ex- 

 panding a little outwards, finely notched or furrowed on the 

 inside of the labial rib ; these notches or furrows are not caused 



* Resembling R. cimex.
