fish for the palinuri with what we call bow-nets or weels. 

 They put in cages of osier the feet of sepiae burnt, with small 

 fishes, crabs, &c. They let them down during the night into 

 rocky places, from fifty to two hundred fathoms deep, and 

 they take in the morning the palinuri which are found there. 

 Their weight is sometimes very considerable. The fishermen 

 are persuaded that they have more flesh at the full moon than 

 at any other time. The extreme fecundity of these Crustacea 

 compensates for the great consumption which is made of them 

 for the table. 



In the maritime towns, they are brought to market still 

 alive ; but they are always cooked when they are to be sent 

 to any great distance, because they die in a short time after 

 they have been taken out of the water, and their flesh quickly 

 putrifies, especially in summer. 



We have figured two undescribed species of decapod Crus- 

 tacea belonging to the Porcellanae of the text. The first 



Porcellana Jiirsuta, is red-brown, rugulose, velvety ; the legs 

 and abdomen fringed with long hairs ; the carpus above flat, 

 rugulose, front edge with five acute triangular teeth, the 

 hinder edge with a series of conical, incurved, short spines ; 

 the front edge of the claw is crenulate at the base ; the fore- 

 head is triangular, bent down, with a small spine over the front 

 edge of each eye. 



The other Porcellana, which is named iiollta, by Gray, is 

 purplish-brown, much polished, and punctulate ; the carpus 

 above is flat, the front edge has three long serrated teeth ; the 

 hinder edge has a spiny ridge near the end; the forehead 

 is triangular, produced, with the margin rather concave. 



To these we have added a figure of the megalope sculpta of 

 Leach, and the megalope maculata of the same naturalist, both 

 of which are yellowish white, and were taken in the Gulph of 

 Guinea.
