A REVISION OF THE AUSTRALIAN TURRIDM—HEDLEY. 311 
PsEUDORHAPHITOMA STYRACINA sp. nov. 
(Plate li., fig. 136.) 
Shell solid, subulate. Whorls ten. Colour uniform grey. Sculpture:— 
Ribs low and broad, with narrow interstices, six on the last whorl; 
spirals are sharp threads running evenly over both ribs and furrows, and 
increasing by intercalation; on the penultimate are four spirals, and on 
the last whorl fourteen, some of which are alternately large and small. 
Aperture:—Sinus U-shaped, rather wide and deep; columella simple ; 
outer lip a thin bent edge; throat grooved within. Length 10 mm., 
breadth 3 mm. 
This has a general likeness to Plewrotoma fortilirata Smith,®* but has 
the base less excavate, the spirals more numerous, and the radials fewer 
and bolder. 
Hab. Queensland :—4 to 14 fathoms, Albany Passage (type) ; off 
Horsey River (self); 10 fathoms, Cape Sidmouth (Henn). There are 
unrecorded specimens of this in the “ Chevert” collection from off Cape 
York and Katow. 
PSEUDORHAPHITOMA TRANSITANS sp. nov. 
(Plate lu., fig. 137.) 
Shell small, solid, biconical. Colour uniform pale buff. Whorls seven. 
Protoconch of two small smooth helicoid whorls. Sculpture :—First adult 
whorl with numerous small radial riblets; on subsequent whorls the ribs are 
spaced seven toa whorl; they are continuous, perpendicular, and elevated ; 
the spirals are prominent cords which project at the intersection of the 
ribs, two on the upper whorls and twelve on the last one, evenly distributed 
from the shoulder to the anterior extremity. Aperture :—Mouth narrow ; 
varix broad and high, of the same calibre as the ribs; sinus small and 
shallow ; within the aperture is a small denticule at each side of the sinus, 
and a small deeply-seated fold on the columella; canal short and wide. 
Length 4 mm., breadth 1°5 mm. 
In general appearance, by short stature and conspicuous spirals, this 
form recedes from typical Pseudorhaphitoma towards Heterocithura. 
Hab. Queensland :—15 fathoms, Palm Islands (self). 
GuRaALeus Hedley. 
Guraleus Hedley, Journ. Roy. Soc. N.S.W., li., 1918, suppl. p. M. 79,

Shell fusiform or subcylindrical, thin. Colour ranging from uniform 
buff, with or without chocolate spiral lines or bands, to entire chocolate. 
Nucleus of two or three smooth helicoid whorls. Fasciole not interrupting 
the sculpture, and scarcely indicated by the curvature of growth lines.
