SOME NEW OR NOTliWOinil Y SHELLS — HEDLEY. 151 



Pyrene intricata, uoDi. mnt. 



Colnmhella clathrata, Brazier, Proc. Linn. Soc. N. S. Wales, 

 i., 1877, p. 229; LL, Hedley, Rec. Austr. Mus., iv., 1901, 

 p. 123, pi. xvi., fif^. 6 (not of Dujardin, 1835, of Guinitz, 

 1875, nor of Tate, 1893, vide Pace, Proc. Malac. 8oc., v., 

 1902, p. 67). 



It has been shown that in Palaeontology the name of Cohim- 

 heUa clathrata has been thrice proposed. As Brazier's choice of 

 tliis name is thereby twice invalidated a substitute is here 

 suggested. 



MUREX PATAGIATUS, Sp. UOV. 



(Plate xliii., fig. 36). 



Shell rather small but solid, biconical. Six whorls remain on 

 the type, which is decollated. Colour cream. Sculpture : there 

 are three varices to a whorl, midway between each pair is a rib 

 almost as prominent as a varix. Fine even spiral threads at the 

 rate of about twenty to the last and eight to the penultimate 

 whorl overrun the shell. These ai'e crossed by a radial system of 

 close fine scales elaborately ])licated in the interstices. Aperture 

 ovate, fortified without by a broad and unbranched varix, on 

 tlie opposite side the inner lip stands clear of the shell for some 

 distance. Canal short and broad. Length of type, 34 ; breadth, 

 18 mm. Another specimen 46 and 26 ram. 



The novelty is clo=ely related to if. denudatus, Perry, but 

 whereas M. denudatus has always two intervariceal ribs, M. 

 patagiatus has, like M. territus, Reeve, but one. Further, as far 

 as limited material permits me to judge, the varices of M. 

 patagiatus are not prone to sprout into fronds like M. denudatus. 

 In being so bare of frills it resembles M. capucinus, Larak. 



Hah. — Type dredged by Mr. J. Brazier in 8 fathoms off Green 

 Point, Watson's Bay, Port Jackson. Two worn specimens were 

 gathered by myself on the beach at Ballina, N. S. Wales. Mr. 

 Brazier's specimen is the only one that I liave seen from the 

 -neighbourhood of Sydney, so the species is rare here and is 

 (probably an intruder from the north.
