Chlokitis silenus, Angas. PI. IV, Fig. 6. 

 Belix silenus, Angas: Proc. Zool. Soc, 1873, p. 182, pi. xx, fig. 2. 



This species is generally larger than C. Gaimardi and has the last 

 whorl compressed above, flattened and sloping towards the periphery ; 

 the aperture is more triangular and relatively higher, the outer 

 margin straight, the basal arcuate, and the columellar sloping, while 

 the umbilicus is more obliquely excavated behind the mouth. The 

 hair-scars are very densely crowded. The enlarged sculpture (PI. IV, 

 Pig. 6) is taken from a specimen from Kew Ireland received by 

 Mr. Ponsonby from Mr. Garrett. It measures diam. maj. 18, min. 

 15'5 mm. ; alt. ITS mm. 



Chloritis conjuncta, n.sp. PI. V, Pig. 5. 



Resembles C. Gaimardi in contour and size, but has the densely 

 crowded hair- scars of C. silenus. It has the spire plane or slightly 

 immersed. Diam. maj. 14-5, min. 13 mm. ; alt. 9'5 mm. 



Mub. — New Ireland. 



Type in my collection. 



The following specimens are in Mr. Ponsonby 's collection : three 

 specimens labelled " Gaimardi;, ex Dr. Cox, Solomon Islands," diam. 

 16-5, alt. 10'5 mm., and diam. 15'5, alt. 10 mm. ; one specimen 

 *^ eustoma, ex Dr. Cox, Solomon Islands," diam. 16, alt. 9-5 mm. ; 

 one specimen "silenus, ex Garrett, New Ireland," diam. 15"5, alt. 

 9'5mm. ; two specimens ^^ silenus = ? Gaimardi, ex Dr. Cox, New 

 Ireland," diam. 15-5, alt. 9-5 mm., and diam. 14, alt. 9 mm.; one 

 "New Ireland," diam. 13-5, alt. 9mm. 



Chloritis fraterna, n.sp. PI. V, Pigs. 6-6c. 



Shell moderately umbilicated, depressed conoid, pale ochreous, finely 

 striated, covered rather sparsely with short, stiff, dark bristles, arranged 

 in quincunx. Spire subplane, suture deep, apex not raised. Whorls 4, 

 increasing slowly, rather tumid above, rounded at the periphery, 

 obtusely angulated round the moderate funnel-shaped umbilicus ; last 

 whorl slightly dilated at the mouth, slowly descending, not deflected 

 in front. Aperture ovate-lunate, a little oblique, pearly within ; 

 margins a little approaching. Peristome dirty whitish, somewhat 

 thickened and expanded, slightly reflected ; upper margin arcuate, 

 outer and basal regularly curved, columellar triangularly dilated and 

 slightly overhanging the umbilicus. Diam. maj. 16, min. 14 mm.; 

 alt. 1 1 mm. 



Hab. — ? New Ireland (ex Sydney Museum). 



Type in Mr. Ponsonby's collection. 



Chloritis fraterna is more elevated in the spire than C. Gaimardi, 

 and has a narrower umbilicus ; the last whorl is not compressed or 

 sloping above, does not descend so deeply in front, and it has a more 

 rounded aperture. C. exigua is more solid, and, although smaller, it 

 possesses half a whorl more, while the hair-scars or pits are much more 

 crowded. Another specimen measures diam. maj. 18, min. 15 mm. ; 

 alt. 12 mm. The shells were received by Mr. Ponsonby as C. silenus.
