1/8 PULMONATA. 



1. Phosphorax NOCTILUCUS. 



Shell thick, oval, white, nearly transparent, smooth above, 

 crystalline beneath. 



Limax noctilucus (L. phosphorescente), D'Orbigny in F&ussae, 



Hist. Moll. ii. 76. t. 2. f. 8. 

 Phosphorax noctilucus, Webb Sf Berth. Ann. Sci. Nat. xxviii. 307. 

 Hab. Tenerifife. 



4. M.\LINO. 



Body slender, obtusely keeled, ending in an acute prism. 

 Head produced. Shield large, anterior, oblique, longitudinally 

 grooved ; front part much produced, concentrically grooved, very 

 contractile, very mobile, and moves rapidly from left to right and 

 vice versa as the animal walks. Orifice of respiration large, 

 rather behuid the middle of the shield. Shell (quite hidden) not 

 described. 



1. Malino lombricoides. 



Slender, flesh-coloured, black-dotted ; body rather rugose ; 

 shield grooved. Shell not described. 



Limax lombricoides, Morelet, Moll. Portugal, 39. t. 3. f. 4. 

 Hab. Portugal. 



Form like Limax agrestis; very vivacious ; singularly elongates 

 the head when walking. 



The genus Oris of Risso {Eur. Merid. iv. 57), arranged by 

 him in Limacides, appears to be a marine animal with foiu* small, 

 not entirely retractile tentacles on the front of the back, and the 

 eyes placed rather above and near the base of the front tentacles. 

 The body is subcylindrical, soft, rather truncated in front, pointed 

 behind, and covered with a very smooth semitransparent fleshy 

 mantle, which edges the foot and covers the head when re- 

 tracted. 



Oris Ferussaci. 



Hab. Nice. In spring, at moderate depth (in the sea?). 



This is evidently not a Limacid, from the position of the eyes 

 and the form of the mantle ; and the combination of characters 

 is so extraordinary, that it requires further examination before 

 it can be referred to any other family.
