Incilaria bilikeata, Benson. 



Corpore livido, velo punctis maculisque fuscis conspersis ornato, 

 lineis duabus lateralibus nigrescentibus, unico obscuriore mediano 

 strigato. 



" # Pound in the earth under the roots of trees. Great num- 

 bers were seen at night above ground on plants and trees, also on 

 rainy days, when they appear suddenly. This slug appears to be a 

 favourite prey of a toad {Bufo gargarizans, Cantor) which swarms at 

 night, and on rainy days, and I once observed a spider, (Latrodectus 

 limacicla Cantor MS,) seize one of these slugs. The Chinese apply 

 the slug as a poultice for bruises, &c. The respiratory orifice is very 

 minute. The sketch represents a good-sized specimen creeping on 

 Slillingia selifera. ' ' 



Helix eavida, Benson. 



Testa subglobosa, umbilicata, epidermide olivacea, anfractibus sex 

 transverse subplicatis, ultimo ventricoso, suturis impressis, umbi- 

 lico mediocri ; apertura suborbiculari elongatiuscula ; labio reflexo, 

 tenui explanato labro acuto. 



Axis 1. 3.— Diam. 1. 33. 



This shell is nearly related to H. pomatia, but has more depress- 

 ed whorls, and a shorter spire in proportion. The apex inclines 

 more to a point than in pomatia. It has not the thickening of the 

 peristome which is so marked in that species. 



The colour, sculpture and smaller size also serve to distinguish it. 

 The length of the aperture slightly exceeds the breadth. The co- 

 lour of the epidermis in the lower whorl is more saturate than in the 

 upper ones. 



" Inhabits trees, mossy stones, rocks, crevices, and the earth ; 

 common at all times in shady places, particularly abundant at night, 

 early in the morning, and on rainy days. The animal is used by the 

 Chinese in headache, and for bruises. The shell is removed, and the 

 animal applied to the suffering part." 



* Dr. Cantor's notes on habitat, locality, uses, &c. are included in the lines with 

 inverted commas.
