PULMONARY. 315 



ones cling to the body of the mother, and remain there until they are able to 

 provide for themselves. 



The Lycosse are extremely voracious, and courageously defend their 

 dwelling. 



A species of this genus, the Tarentula, so called from Tarentum, a city of 

 Italy, in the environs of which it is common, is highly celebrated. The 

 poisonous nature of its bite is thought to produce the most serious conse- 

 quences, being frequently followed by death or Tarentism, results which can 

 only be avoided by the aid of music and dancing. Well informed persons, 

 however, think it more necessary in these cases to combat the terrors of the 

 imagination than to apply an antidote to the poison; medicine at ah 1 events 

 presents other means of cure. 



In the second section of the Vagabundse, that of the SAI/TIGRAD.S:, the 

 eyes form a large quadrilateral, the anterior side of which, or the line 

 formed by the first ones, extends across the whole width of the thorax; 

 this part of the body is almost square or semi-ovoid, plane or but slightly 

 convex above, as wide anteriorly as in the rest of its extent, and descending 

 suddenly on the sides. The legs are fitted for running and leaping. The 

 thighs of the two fore legs are remarkable for their size. 



The Araignee a. chevrons blancs of Geoffroy, a species of Salticus very com- 

 mon in summer on walls or windows exposed to the sun, moves by jerks, stops 

 short after a few steps and raises itself on its fore legs. If it discover a fly, 

 or particularly a musquito, it approaches softly, and then darts upon the victim 

 with a single bound. It leaps fearlessly and perpendicularly on a wall, being 

 always attached to it by a thread, which lengthens as it advances. This same 

 filament also supports it in the air, enables it to ascend to its point of depar- 

 ture, and allows it to be wafted by the wind from one place to another. Such, 

 generally, are the habits of the species that belong to this division. 



Several construct nests of silk resembling oval sacs open at both ends, between 

 leaves, under stones, eS^c. Thither they retire to change their tegument and to 

 seek shelter in bad weather. If danger menaces them there, they leave it at 

 once and escape with speed. 



The females construct a sort of tent, which becomes the cradle of their 

 posterity, and in which the young ones, for a time, live in common with the 

 mother. There are several subgenera. 



FAMILY II. 



PEDIPALPI. 



IN the second family of the Pulmonaria?, we find very large palpi, re- 

 sembling projecting arms, terminated by a forceps or a claw; didactyle 

 chelicerae, one finger of which is moveable, and an abdomen composed of very 

 distinct segments, without fusi at the extremity. The whole body is invested 

 with a firm tegument; the thorax consists of a single piece, and exhibits three
