 Sunda. 



C. Straight species : the orifices distant ; the envelope of a single 

 piece ; aggregation circular. 



S. jiinnala. The body is marked with two dorsal lines, one yellow, 

 the other white, and on each side of the belley is a violet line. Thero 

 is also a variety with interrupted lateral lines. It is found in the 

 Mediterranean Sea.

 gation reaching more or less beyond the apertures.

the combined contractions and dilatations of all the iinlividn.il 

 animals which compose it. The branchial orifices are pierced near 

 the points, and the anus opens into the interior cavity of the tube. 

 Thus, says Cuvier, one may compare a Pyroioma to a great number of 

 stars of Bolrylli rBoTRYU.CS] strung one after the other, but the 

 whole of which would be moveable. 



Mr. George Bennett, in his interesting 'Wanderings in New South 

 Wales,' after some remarks on the luminosity of the ocean says, ' On 

 the 8th of June, being then in latitude SO' south, and longitude 

 27 5' west, having fine weather and a fresh south easterly trade-wind, 

 and the range of the thermometer being from 78 to si 1 ', late at 

 night the mate of the watch came and called me to witness a very 

 unusual appearance in the water, which he, on first seeing, considered 

 to be breakers. On arriving upon the deck, this wai found to bo a 

 very brood and extensive sheet of phosphorescence, extending in a 

 direction from east to west as far as the eye could reach ; the lumino- 

 sity was confined to the range of animals in this shoal, for there was 

 no similar light in any other direction. I immediately cast the 

 towing-net over the stern of tho ship as we approached nearer the 

 luminous streak, to ascertain the cause of this extraordinary and so 

 limited a phenomenon. The ship soon cleaved through the brilliant 

 mass, from which, by the disturbance, strong flashes of liglr 

 emitted ; and the shoal (judging frum the time the vessel took in passing 

 through the mass) may have been a mile in breadth ; the passage of 

 the vessel through them increased the light around to a far stronger 

 degree, illuminating the ship. Ou taking in the towing-net it was 

 found half-filled with Pyroioma (Atlanlicum !), which shone with a 

 beautiful pale-greenish light, and there were also a few small fish in 

 the net at tho same time ; after the mass had been passed through, 

 the light was still seen astern until it became invisible in the distance, 

 and the whole of the ocean then became hidden in darkness u before 

 this took place. The scene was as novel as it was beautiful and interest- 

 ing, more so from having ascertained, by capturing the luminous 

 animals, tho cause of the phenomenon." On a second occasion Mr. 

 Bennett took in the towing-nct a number of Pyrotoma Atlantic urn, 

 whilst the sea was phosphorescent. 



Preparations of these curious animals will be found in the Museum of 

 the Royal College of Surgeons . l England. [TU.MCATA ; MOLMJSCA.] 



SAL&IFY. [TnAGOPOooN.J 



SA'I.soLA, a genus of 1 huts belonging to the natural order 

 Chenopodiaeea, so named from ' nalsus,' salt, in consequence of many 

 of the species yielding kelp and barilla. The specie* are chiefly found 

 on the sea-shore in temperate part* of the world, and also in hot parts 

 of tlie world where the soil is saline, or there is salt water in the 

 vicinity. The genus is characterised by having perfect flowers ; the 

 perianth .1 cleft, persistent, enveloping the fruit with its base, and 

 crowning it with its enlarged scaiiose limb; stamens 5; styles 2; 

 emliryn spiral; berb< or small shrubs, smooth or pubescent; loaves 

 alternate or opposite, roundish, seldom flat ; flowers axillary and 

 sessile.
