SCAEABUS.— Plate III. 



Pyramidal in form, but chiefly distinguished by its 

 rounded golden-red aperture. 



Species 24. (Mus. Cuming.) 



Scarabus Argenvillei. Scar, testa pyramidali-oblongd, 

 angusld, compressiusculd, albidd, rubido-castaneo len- 

 tiginosd, anfractibus novem ad decern, longitudinaliter 

 corrugato-striatis ; aperturd ovatd, superne moderate 

 angulalo-emarginatd. 



Argenville's Scarabus. Shell pyramidally oblong, 

 narrow, rather compressed, whitish, freckled with 

 reddish-chestnut, whorls nine to ten, longitudinally 

 wrinkle-striated ; aperture ovate, moderately angu- 

 larly notched at the upper part. 



Hab. ? 



Of a narrower and more oblong pyramidal form than 

 the preceding species, while the aperture, it will be seen, 

 is altogether different. 



Species 25. (Mus. Cuming.) 



Scarabus inflatus. Scar, testa globoso-trigoud, subin- 

 flatd, fulcd, lirido-purpnred, obscure fasciatd, spird 

 brevi, anfractibus octo, dense minute corrugato-stria- 

 tis, ultimo abrupte angulato ; aperturd oblique ovatd, 

 margine conspicue effusd. 



The inflated Scarabus. Shell globosely triangular, 

 rather inflated, fulvous, obscurely banded with livid- 

 purple, spire short, whorls eight, densely minutely cor- 

 rugately striated, last whorl abruptly angled ; aperture 

 obliquely ovate, conspicuously effused at the margin. 



Pythia inftata, Pfeiffer, Zeitschrift fur Malak. 1853, 

 p. 192. 



Hull, Borneo. 



A fine bold example of the abruptly-angled type of the 

 genus. 



Species 26. (Mus. Cuming.) 



Scarabus striatus. Scar, testa ovatd, fulvescenle, rufo- 

 castaneo nebulaid, anfractibus octo ad novem, longitu- 

 dinaliter ritgato-striatis ; aperturd subquadrato-oratd, 

 subprominente effusd. 



The striated Scarabus. Shell ovate, fulvous, clouded 



with reddish-chestnut, whorls eight to nine, longitu- 

 dinally wrinkle-striated ; aperture somewhat squarely 

 ovate, rather prominently effused. 



Beeve, Ann. and Mag. Nat. Hist. 1842, p. 220. 



Hab. San Nicholas, Island of Zebu, Philippines ; Cuming. 



This is not a satisfactory example of the species. Por 

 a figure of the original type see Conch. Syst. vol. ii. 

 pi. 188. f. 9. 



Species 27. (Mus. Cuming.) 



Scarabus avellana. Scar, testa subquadrato-ovatd, 

 compressiusculd, livido-castaned, vix maculatd, spird 

 brevissimd, anfractibus septem ad octo, longitudinaliter 

 tenue ritgato-striatis ; aperturd quadrato-ohlongd, sit- 

 perne subangulato-emarginatd, inferne effusd. 



The filbert Scarabus. Shell somewhat squarely ovate, 

 rather compressed, livid-chestnut, scarcely blotched, 

 whorls seven to eight, longitudinally finely wrinkle- 

 striated ; aperture squarely oblong, slightly angularly 

 notched at the upper part, effused at the lower. 



Hab. Island of Madura, near Java. 



The accompanying figure of this species, which is a very 

 characteristic one, fully illustrates it peculiarities. 



Species 28. (Mus. Cuming.) 



Scarabus plicatus. Scar, testa oblique trigond, fulves- 

 cente, livido-purpureo iinctd et fasciatd, spird brevi, 

 anfractibus septem ad octo, minutissime corrugato- 

 striatis, ultimo snbabrupte angulato ; aperturd oblique 

 quadratd, conspicue effusd. 



The folded Scarabus. Shell obliquely triangular, ful- 

 vous, stained and banded with livid-purple, spire 

 short, whorls seven to eight, very miuutely wrinkle- 

 striated, last whorl rather abruptly angled; aperture 

 obliquely square, conspicuously effused. 



Perussac, Prodrome, p. 101. 

 Auricula plicala, Deshayes. 

 Scarabus triangularis, Benson. 



Hab. India; Benson. Jaffna, Jaffnapatam, Ceylon (in 

 saline marshes) ; Gardner. 



This and S. Ceijlanicus, inhabiting Ceylon, belong to a 

 very characteristic type of the genus represented in Borneo 

 by -S. inflatus.
