18/8.] MR. E. A. SMITH ON A HELIX FROM JAPAN. 105 



The syrinx (fig. 2, p. 104) is Columbine, with its lateral muscles 

 attached inferiorly to the membrane between the penultimate aud 

 antepenultimate tracheal rings. The trachea is composed of rin^s 

 which are very yielding in the middle line posteriorly. As can be 

 seen in the figure, the musculi sterno-tracheales, which are inde- 

 pendent of the intrinsic muscles, are not quite symmetrically attached 



Ihe furcula, as is the rule in the subfamily, is very slender but 

 complete, wherein this species differs from Phcenorhina goliath, in 

 which it is cartilaginous at its symphysial end, according to MM 

 Verreaux and Des Murs \ 



Myologically, the ambiens is to be found, not large ; the femoro- 

 caudal with its accessory head are well developed ; the semitendinosus 

 and its accessorius are the same. 



There are two carotids ; so that in this as well as all the other 

 features above mentioned Carpophaga latrans agrees with my 

 definition of the division of the Columbidse into which it naturally 

 falls, its gizzard differing, however, from that of all but one of the 

 species which have been examined. 



9. Description of a new Species of Helix from Japan. 

 By Edgar A. Smith, F.Z.S. 



[Eeceived December 4, 1877.] 

 Helix (Camena) congener, n. sp. 



Testa convexiusculo-orbiculata, spira breviter conica, subaperte 

 umbihcata, tenuis, sordide pal/ido-virescenti-albida, fasciis 

 tribus nigrofuscis, media latissima, infima umbilicum pingente ; 

 anfractus 5|, convexiusculi, lineis incrementi obliquis flexuosis 

 strusque spiralibus confertis insculpti, ultimus subtus satis con- 

 vexus, prope aperturam leviter breviterque descendens ; apertura 

 perobhqua, semilunaris, intus fasciata ; peristoma tenue, rosa- 

 ceum vel hhaceum, marginibus conniventibus, supero breviter 

 expanso, basali et columellari latius reflexis. 

 Diam. max. 30 mill., min. 25, alt. 18 ; aperturse long. 15,lat. 14

 showing its distinctness.

 the banding in the fourteen specimens examined invariably follows 

 the same arrangement, and not one of them exhibits any trace of the 

 opaque yellow stripes or blotches which are almost invariably ob- 

 servable in a greater or less degree (on the bands most conspicuously) 

 in H. peliomphala. JJ 



This is a very pretty, delicate species, and of a thin semitransnarent 

 texture. On the front of body-whorl, about two thirds of its whole 

 extent from the lip, there is an obliqiie strongly marked line which is
