Z THE NAUTILUS. 



Veronicella mexicana betheli v. nov. 



Above, warm red-brown, paler toward the sides, with scattered 

 pale dots ; dorsal and subdorsal regions irregularly and not densely 

 speckled with blackish ; on the anterior third this speckling is re- 

 solved into a pair of obscure bands, a little nearer to each other than 

 either to the lateral margin. Beneath pale reddish, darker poster- 

 iorly, and speckled with pale. Sole pale ochreous. Tentacles dark 

 grey. There is not the slightest indication of a pale dorsal line. 

 Under a lens, it is seen that the body above and below (especially 

 posteriorly below) is very closely beset with minute pale dots, which 

 correspond with punctiform depressions, while over this pattern are 

 set numerous much larger diffused pale spots. All this is hardly to 

 be noticed without magnification. Length (at rest) about 50 mm., 

 breadth in middle about 23 ; breadth of sole 9 mm.; of body on each 

 side of it 7 mm., sole not projecting beyond body. 



The above was from the living slug. In alcohol it appears as fol- 

 lows: Length 34, breadth 18 mm.; width of sole 7 mm.; female 

 orifice 19 mm. from anterior end, 16 from posterior, only one mm., 

 from sole ; sole with about 7 cross-stria? in one mm.; end of sole 

 broadly rounded, about 2 mm. from hind end. Jaw strongly arched, 

 with about 25 strong ribs ; teeth about 54-1-54, ordinary, middle 

 tooth reduced, shaped like a spear-head, marginals quadrate ; salivary 

 glands normal, pale yellow ; oasophagus longitudinally corrugated ;. 

 stomach with a portion having a diameter of about 2 mm. not covered 

 by liver; albumen glands large, bright orange-yellow; receptaculum 

 seminis oval, yellowish-plumbeous, about 1.25 mm. long ; accessory 

 glands about 38, of which about 24 are 11 mm. long, the others- 

 variously shorter, several only half as long. 



A PHILOMYCUS FROM THE REPUBLIC OF PANAMA. 



BY T. D. A. COCKERELL. 



During a recent visit to Central America, Mr. E. Bethel found

 Panama. The genus is new to Panama. Two specimens are evi-

 other is immature. The slug may be described as follows :
