11 I .I.IO'PORA, a genus of stony PoJjrptorio, established by De Blam- 

 ille, from observations of Messrs. Quoy and Gaimard on a recent 

 pecies called by Lamarck Poci'lopora armlta. 



It U characterised as follows : Animal short and cylmdncn 

 ided with a simple circle of thick tentacula, 15 or 16 in number, 

 contained in vertical or diverging cylindrical cells ; cells immersed, 

 itrmally crenulated by imperfect radiating lamelhv, united into a 

 calcareous mass, which is regularly porous in the intervals of the 

 cells. The coral is found attached to various bodies. 



Three recent species are mentioned by De Blainville, all from warui 

 mras. One of the fossil species (Htliopora poroin, De BL ; //. inler- 

 tincta, Bronn) abounds in strata of the Silurian syst. : 

 , -ur in the chalk and in tertiary deposits. (' Manuel d'Actinologia') 

 HKI.IOHNIS, llonaterre's name for a genus of Water-Birds (Grtbi- 

 oulques of Buffon), which have lobated feet like the Coota and Grebes, 

 >ut with a greater development of tail, and they have sharper claws.

II KUOTROPE. [BLOOD-STOXK.] 



H KUOTUO'PIUM (from <Aiof, the sun, and Tfxnrii, a turning), a 

 genus of Plants belonging to the natural order fliretiacttc. It has a 

 ialver-shaped corolla, with the throat usually naked, but in some species 

 warded ; the segments of the limb furnished with a single fold or a 

 tooth between each ; the stigma sub-conical ; the carpels 4, 1-cclled, 

 combined, closed at the base, without any manifest receptacle. The 

 pecies are annual or shrubby plants, with alternate leaves, and 

 circulate spikes of small blue or white flowers. 



II Peruvianum, Peruvian Heliotrope, or Turnsole, has a shrubby 

 stem, petiolate oblong-lanceolate wrinkled leaves, terminal branched 

 spikes ; the tube of the corolla hardly the length of the calyx. 

 The mouth of the corolla is intersected with five plicatures of a 

 purple-lilac colour, with a greenish throat. It is a shrub, growing 

 >ne or two feet high, and is much cultivated on account of the scent of 

 its flowers, which resembles very much the smell of the vanilla or 

 cherry pie. It is a native of Peru. 



II. I'uropfrum, the European Turnsole or Heliotrope, lias an herba- 

 ceous erect stem, with ovate flat-lined finely tomentose leaves, the 

 ateral spikes solitary, the terminal ones conjugate, the calyx spread- 

 ing in the fruit-bearing state. It is a native of the south of Europe 

 and the regions of the Caucasus. The flowers are sweet-scented. Tho 

 .eaves were formerly used medicinally. 



//. rillonm has an herbaceous erect very villous stem, with ovate, 

 flat, villous leaves ; the spikes lateral, terminal, solitary, and conjugate ; 

 the corollas large; the calyx spreading in the fruit-bearing stat 

 is a native of Greece and of the islands of tho Archipelago. It Iws 

 large white corollas with a yellow throat This appears to bo tho 

 'H\urTf4wtoi> fitya of Dioscorides (iv. 190) and the //. IM/.IMI, the 

 'HAiorpoVioy puKpir. 



Upwards of 80 species of this genus have been .num. r it d. 

 are natives of the warmer parts of Europe, Asia, Africa, and An 

 and are found in Australia. They do not possess any active properties. 



Many other species besides those here described have sweet-scented 

 flowers, and arc cultivated on that account. Some of Hi 

 Hiunud iii largo quantities by perfumers for tho sake of their v 

 oil. They are astringent and also mucilaginous, and pOultiOM madr

II i:i. IX (Limucus), a genus of Pulmoniferous Molliura, embracing 

 the various forms of animals called Snails. The following are the 

 characters of this genus: Shell spiral, opaque, or translucent, solid 

 or thin, more or less globose, in some discoid, smooth or sculptured ; 

 surface variously coloured, but seldom covered with a polished 

 epidermis ; mouth lunated, thickened within, simple or toothed ; 

 -ne frequently reflcxed. Animal moderately Urge in propor- 

 tion to shell ; head with four developed tentacles ; mantle i 

 on shell; tail lanceolate and never truncate; foot often ample; 

 tongue with the edge teeth serrate. (Forbes and Hani. y. ) 



The species of this genus, at the approach of winter, ..r in \ .TV dry 

 weather in summer, recede into their shell, and secrete a quantity of 

 mucus, which forms a covering over the aperture. Thin thickened 

 matter, which the animal has the power of throwing off by producing 

 fresh mucus within, is called an ' epiphragm.' The power of forming
