HELIANUS, a genus of Fishe. belonging to the ScueniJir, a family 

 of Arnntkopteryyi*- 



HBLICARION. [HEUCIDA] 



IIKU'CID^E, a family of Gasteropodous JUoUtuca to which the 

 land Shell-Snails are referred. 



Dr. J. }'.. liny, in hi* paper on 'Streptaxis' ('Magazine of Natural 

 History,' vol. i.), observe, that zoologist* have divided land-shell.* into 

 several genera ; but that the late Baron FuVuasac united most of them 

 into a .ingle genus, as he wished to establish as a rule that all tin- 

 genera of Molltuca should be alone characterised by some peculiarity 

 in th- animal. " The increased knowledge," continue. Dr. Gray, " of 

 the animal has shown that some of the species which he (Ffrussao) 

 referred to the genus Iltlit have very different animals from the 

 typical kinds ; and it is probable that eventually several of the genera 

 established before his time (which he attempted to set aside) will be 

 found to be true genera, according to his own theory. The knowledge 

 of the animal, and the history of several specie* which were unknown 

 at the time he wrote his system, have shown that several of the cha- 

 racters which he considered as of generic importance are common to 

 other specie, belonging to quite different group*. Thus we now kuow 

 that *ome Helicn (Carocolla inrerticolor, Baled CArmni/.-ii, and some 

 other.) are viviparous, as well a. the Pariulte ; that the degree of 

 development in the lower pair of tentacles is variable in the different 

 pecie* of Pupa and Vtrtiyo ; and that to separate the latter genus 

 from the former, on account of the partial obliteration of these organ*, 

 ha* the effect of dividing very nearly allied specie*. I am inclined to think 

 that theae and numerou* similar facto, which must be well known to 

 every practical conchologist, show us that we are warranted in establish- 

 ing genera from any peculiarity in the structure or form of a aerie* 

 of shell*, u well as on a peculiarity in the animal alone ; especially 

 when we consider how very few of the animals of the different specie* 

 which we are called upon to arrange are or ever can be known ; and 

 also, as we constantly find by experience, that every peculiarity in the 

 form or structure of the shell is the indication of some peculiarity 

 in the habit or organic structure of the animal which formed it, 

 and warrant* it* separation from the rest of the specie* of the 

 family." 



The organisation of this group of animals may be illustrated by the 

 structure of the large Roman Snail (Ilrlit Pomatia), of which there 

 are several preparation, in the museum of the Royal College of 

 Surgeon* in Ixmdoti. 



Nutrient Organa, In the Physiological Series Gallery, No. 301, 

 is a preparation of the Helir Pomatia, Linn., showing the form of the 

 mouth and the part which performs the office of teeth. This is a 

 dentated horny substance, of a dark colour and arched form, situated 

 transveraely above the aperture of the mouth, and funning, as it M.I-., 

 the margin of the upper lip ; the lower lip is divided by a vertical 

 nature. No. 302 of the same series shows in the head of another 

 Sh.-ll. Snail the same structure of mouth. No. 767 shows the soft part, 

 of Helix Pomatia, and the alimentary canal has b.-en injected with 

 ire and vermilion; to that the salivary glands, from their wliit.- 

 colour, may be distinctly perceived upon the parietes of the sU>in:ic'li. 

 Theae gland, an of a flattened, elongated, and irregular form, ami of 

 a conglomerate structure; they may be seen diminishing in !>< 

 as they extend upwards towards the pharynx, where their duct* 

 terminate. Here also the semicircular dentated homy jnw, the 

 course and termination of the alimentary canal, and the position :>n.| 

 form of the liver, are well displayed. The next preparation (No. 768), 

 which exhibit* the mouth, oesophagus, and t>.m:ii -li of the name 

 pecie*, show, the junction of the two wilivary glands at their lower 

 rxtn-iiiitiea, and the termination of their ducta. The oesophagus and 

 stomach being laid open, their internal structure is seen. (' Catalogue '
