Troclionanhia paraguensis, Smith, Ann. Mag. Nat. Hist. 1893, 

 vol. xi. p. 349, pi. xviii. figs. 7-9. 



Hah. Balabac and Palawan. 



The specimens from Balabac offer no variation from those 

 occurring at Palawan. A small variety, 13 millim. in diameter, 

 occurring at the latter island, has the same number of whorls, but 

 the spire a little more conical than the type.

 Diam. maj. 18| millim., min. 17, alt. 7|. 

 Hah. Banguey Island. 



This species is of a uniform brown tint above and below, and 

 the thickened lip is pale rose. The spiral sculpture on the upper 

 surface extends over the whorls and is finer than in T. paraguen- 

 sis. The shell also is a little more compressed, and the body-whorl 

 is narrower, and with only feeble traces of spiral striae beneath. 



13. Trochonanina hebaclea. (Plate II. fig. 12.) 



Testa T. bongaoensi affinis, sed spira magis conica, anfractibus 

 lentius accrescentibus, idtimo latiore, lineis spiralihus et incre- 

 menti validioribus. 



Diam. 17 millim., alt. 8. 



Hah. Mount Rabong, West Sarawak. 



A trifle larger than T. bongaoensis (Ann. & Mag, N. H. 1894, 

 vol. xiii. p. 52, pi. iv. tigs. 2-2 6), but of the same brown colour and 

 general appearance. The lip is rosy white and tortuous as in 

 T. bongaoensis, but the spire is not convexly conoidal, but with 

 rectilinear sides, the increase and width of the whorls are different, 

 and the spiral sculpture is stronger. 



14. Trochonanina kxna-baluensis. (Plate II. figs. 15, 16.) 



Testa imperforata, depressa, acute carinata, rufo-castanea, stipru 

 fortiter spiraliter striata, infra lineis incrementi modo striata ; 

 spira conica, parum elata ; anfractus 7, supremi pjallidi, con- 

 vexiusculi, ca'teri planiuscidi, supra suturam albo-marginatam 

 leviter impressi, incrementi lineis et striis spiralibus sculpti, 

 idtimus acutissime carinatus, infra convecciusculus, prope 

 carinam impressus ; apertura angidatim lunaris, margine 

 hasali conspicue incrassato et leviter rejiexo, ptirpureo-rufo, ad 

 insertionem pallida, paulo dilatata, margine superiore tenui. 



Diam. maj. 23*5 millim., min. 21, alt. 10.
