GUDE : ON CHLORITIS. 45 



overhanging the moderate, deep umbilicus. Dium. maj. 22, min, 

 18 mm. ; alt. 14 mm. 



Hah. — German New Guinea. 



Type in Mr. Ponsonby's collection. 



A thin fragile species somewhat resembling C. eustoma in contour, 

 but the umbilicus is much narrower and not funnel-shaped, the last 

 ■whorl descends more deeply in front, the suture is less deep, and the 

 last whorl is slightly constricted behind the mouth. It also appears 

 to be allied to C. Simbange^isis, Kobelt (Nachrichtsblatt Deutsch. Malac. 

 Ges., 1898, p. 93), to which I was at first inclined to refer it. 

 I forwarded a specimen to Professor Boettger for comparison with the 

 type of that species, if he had access to it, and he obligingly informed 

 me that the type was contained in the collection of the late Bruno 

 Strubell, part of which passed to Herr Biilow, who, however, cannot 

 find it. From the description, C. Simhangensis appears yellowish 

 white, the whorls plane near the suture, subangulated at the periphery, 

 and descending deeply in fi'ont, which characters are wanting in the 

 new species.

 p. 316. 



The last portion of the penultimate and the whole of the last whorl 

 are obtusely angulated, and flattened near the suture ; the last whorl 

 is also obtusely angulated below round the funnel-shaped umbilicus ; 

 these features, not mentioned in the original diagnosis, connect the 

 species with C. eudoma. From Mr. Ponsonby I have received two 

 specimens labelled " C discordialis, New Ireland; ex Mus. Sydney," 

 which I refer to Mr. Fulton's species; they are pale brown with 

 a pale fuscous peristome, and one of them is slightly more depressed 

 in the spire. Three specimens received from Mr. Fulton, " ex Dr. Cox's 

 collection," and considered by him to pertain to C. erinaceus, I also 

 refer to C. tenebrica. One is pale fuscous with a dirty whitish lip ; 

 it possesses 5 whorls, and measures 27 mm. in diameter, alt. 21 mm. 

 The two others are darker with violaceous peristome ; the angulation 

 near the suture is less pronounced; they measure 22mm. in diam., 

 15 alt., and 22 mm. diam., 16-5 alt. respectively. For these I propose 

 the varietal name pallida. 



Two bleached specimens, labelled " C. tenehricn, var., New Ireland," 

 also from Mr. Fulton,, have the umbilicus narrower and the angulation 

 obsolete, while the last and penultimate whorls are rounded above, 

 not angulated. This form may be called var. tumida. 



Chlokitis fausta, n.sp. PI. IV, Figs. b-bc. 

 Shell widely umbilicated, depressed conoid, shining under a 

 deciduous velvety cuticle, earlier whorls pale fuscous, becoming- 

 reddish brown on the last whorl, faintly striated, covered with slight 

 tubercles arranged in quincunx, which, in fresh specimens, are 

 furnished with short dark bristles. Spire plane, suture deep. 

 "Whorls 4:^, increasing regularly, the last rather suddenly, tumid and 

 subangulated above, rounded at the periphery, obtusely angulated
