Mollusks. 5105 



watering informed me that the worms had been disgorged by the 

 slugs. One slug was considerably larger than the others, in which, 

 on cutting it open, I found a large worm. During fine mild weather 

 I observed one on the surface of the ground, firmly fixed to the middle 

 of a large worm, the head of the slug being so buried in it that it ap- 

 peared to be nearly cut in two : it appears to me, however, that they 

 generally contrive to seize them by one end ; otherwise it would be 

 difficult to swallow them whole, as they do ; and I think there is no 

 doubt that they generally get hold of them under ground, as the one 

 above mentioned had most likely been dragged to the surface by the 

 worm. I determined, however, to watch its motions, but a heavy rain 

 coming on prevented me, and when the shower ceased they had both 

 disappeared. 



"A few days ago one was turned up with a spade, having hold of 

 a worm by the head, with about half an inch of it swallowed. The 

 worm appeared quite alive and strong, and turned the slug over with 

 every twist of its body. The slug kept its hold for some time, but 

 ultimately quitted it, probably in consequence of being disturbed. 

 In digging up the specimens one of them was cut with the spade, in 

 which a small slug was found of the common species." 



This species has been observed never to feed on vegetables. It is 

 very tender, and was seldom found by Mr. Blair away from the green- 

 house. 



Figures. — This species is figured in Loudon's Mag. Nat. Hist. vi. 

 45, and vii. 224; and in Sowerby's 'Genera of Shells.' 



T. Ambiguus, Ferussac. 



Animal. — (Unknown). 



Testa. — Depressiuscula, fragilis, subtiliter striata, pallide viridis ; 

 spira indistincta; apice occultata; apertura amplissima, simplici. 



Mr. Sowerby does not consider T. Ambiguus a species, inas- 

 much as the shell has every appearance of an internal one. 



T. Medii Templi, Thomas Tapping. 



Animal.— Flavidum rufum, maculatum multis brunneis labeculis, 

 tentaculis quatuor nigris et cylindricis. 



Testa. — Fusca, exilis squamea, fragilis, subtiliter striata; apice 

 occultata ; apertura amplissima. 



This species, which I propose to call T. Medii Templi, from the 

 gardens in which it was discovered, is of a bright yellow, dusted over 

 with minute brown specks which are scarcely visible. It is slug-like,
