GUDE : ON CHLOIilTIS. 49 



I am able to separate at least three forms which appear to deserve 

 specific rank. The type of Pfeiffer's species in the British Museum 

 has the spire elevated, not flattened ; and the rows of hairs are more 

 distant than in the allied forms. I give an enlarged view of part of 

 the periostracum near the mouth from one of Mr. Ponsonby's 

 specimens. The figures in Cox's Monograph, pi. v, fig. 2, and 

 lleevc's Conch. Icon., fig. 777, are badly drawn, and it is impossible 

 to say what species they represent. 



Chloritis novocambrica, n.sp. PI. V, Figs. 2-2c. 



Shell narrowly umbilicated, depressed, pale cinnamon brown, finely 

 striated, covered with very crowded, short, stiff bristles, arranged in 

 quincunx. Spire shortly conoid, suture shallow, apex obtuse. 

 Whorls 4i to 4^, a little flattened above, rounded at the periphery, 

 slightly compressed below, the umbilicus a little obliquely excavated 

 behind the mouth and subangulated ; last whorl shortly deflected in 

 front, slightly constricted behind the mouth. Aperture suboval, 

 oblique, margins slightly approaching ; peristome white, thin, slightly 

 expanded, margins arcuate, columellar margin dilated above, and half 

 covering the narrow umbilicus. Diam. maj. 13-5, min. ITomm. ; 

 alt. 8'5 mm. 



Hah.—'^QW South Wales. 



Type in Mr. Ponsonby's collection. 



Similar in shape to C. brevipiU, but twice the size, and with the 

 hairs much more crowded. 



Chloeitis disjuncta, n.sp. PI. V, Figs. 3-3c. 

 Chloritis brevipila, Pilsbry : Man. Conch., vol. vi, pi. Iviii, figs. 28-30 

 (not of Pfeiffer). 



Shell moderately umbilicated, depressed, pale corneous, finely 

 striated, covered with pits or hair-scars, arranged in quincunx, in 

 fresh specimens probably provided with short hairs. Spire low conoid, 

 suture impressed, apex obtuse. Whorls 4, rounded above, swollen 

 below, subangulated at the periphery, becoming rounded towards the 

 mouth. Last whorl shortly deflected in front, scarcely constricted 

 behind the mouth. Aperture suboval, oblique ; peristome thin, a little 

 expanded ; margins convergent, curved, columellar margin dilated, 

 and impinging upon the moderate pervious umbilicus. Diam. 8-9, 

 alt. 5-5^ mm. 



Eah. — Port Stephen, New South Wales. 



Type in Mr. Ponsonby's collection. 



Allied to the last species, but smaller, with less crowded hair-scars, 

 and wider umbilicus. Compared with C. brevipila it is smaller, the 

 spire more elevated, the umbilicus slightly narrower, and not excavated 

 or angulated, and the hair-scars more crowded. 



Chlokitis Layaedi, n.sp. PI. Y, Figs. 4-4e. 

 Shell moderately umbilicated, depressed, pale to reddish brown, 

 smooth, with a velvety cuticle, covered with rather distant rows of 

 short, stiff, dark bristles, arranged in quincunx. Spire plane, suture
