94 Dr. Philippi on a new Species of wood-boring Crustacea. 



have I succeeded in obtaining it in a fresh state. M. Scacchi 

 however has been so fortunate and has kindly lent me the 

 drawing, which I shall subsequently publish if I find it im- 

 possible to sketch one myself from the living animal. The 

 animal according to this drawing has not the least similarity 

 to the false one of Donati, nor even with that of Shaw\ Its 

 colour is of a dirty yellow falling slightly into orange yellow, 

 and it presents about thirty tentacula standing apparently 

 in two series. Each one is 3|'" long, nearly 1'" thick at the 

 base, and gradually tapering towards the apex, which is not 

 clavately thickened. At some distance downwards from the 

 tentacula, and extending about 3^" to 4'^' in breadth, is the some- 

 what thick and fleshy body which exhibits numerous oblique 

 furrows and as many strong longitudinal furrows as there are 

 tentacula in one row, and then suddenly gives place on the 

 drawing to the thin membrane which covers the coral stem. 

 The mouth projects very considerably, nearly 5'" between the 

 tentacula, but it can also be greatly retracted. It measures 3^'" 

 in diameter, and is surrounded by numerous longitudinal folds.

On the 17th of May I found at Trieste near the Lazaretto 

 Vecchio several planks just drawn from the sea, which were 

 eaten through and through, so that they nearly wore the 

 aspect of a sponge. The holes were of two kinds ; the larger 

 ones of at least 2'" in diameter, in which were a quantity of 

 oviferous Teredo navalis, and the smaller of about |'" in dia- 

 meter, in which I found the little crustacean, which will pre- 

 sently be described, in such immense numbers that I could 

 not doubt for a moment that these holes and galleries had ori- 

 ginated from their devouring. Now if it was already inter- 

 esting to me to find a second example of a wood-boring crus- 

 tacean, my joy at this discovery was greatly increased from 

 its not belonging, like Limnoria, to the Isopodes, but being 

 an Amphipode, and moreover strikingly distinguished from all 

 others by its antennae and more especially by its remarkable 

 tail. A great number of specimens have reached Cassel in 

 safety, and I only brought two accidentally with me to Naples^ 

 from which I have drawn out preliminarily the following de-
