Thorace fere dimidio longiore quam latiore, fronte latissima, truncata, desinente in duobus parvis 
tuberculis quae ad basilarem articulum antennarum exteriorum fere pertinent; dente validissimo ad partem 
ateralem thoracis, spatio satis magno post oculos; pedibus prioribus cylindricis, digito parum valido desinen- 
tibus, paululum mtrorsum curvatis, ad margmes denticulatis, cavis punctis in sulco, tertio pedum pari

Carapace about as long again as wide, front very wide, truncated, and terminatino- in 
two little tubercles which nearly extend as far as the basilar joint of the external antennae; 
a very strong tooth on the lateral part of the carapace at some distance behind the eyes 
Fore-legs cylindrical, terminated by a weak pincer, slightly curved inwards, denticulated 
at the edges with hollow puncta in the groove, the third pair of legs nearly twice as long as 
the body. 5

The Camposcia retusa, in its young state, has the carapace smooth and shining and the 
legs, which appear rather slender, are but slightly tomentose ; as it advances in life the 
carapace and legs become covered with a thick, woolly, yellowish-brown tomentum, and, in 
advanced age, the entire animal is concealed by a covering of Sponges, Corallines, AUas, 
Actiniae, and Alcyoma, beneath which it is impossible to recognise the species. The dissimilar 
aspect presented by this species, under these various conditions, is splendidly illustrated by 
a suite of specimens in the collection of the British Museum. J 
The species is widely distributed, and the materials with which their bodies are covered 
appear to depend upon the localities in which they are found. Specimens from the Mauritius 
are covered with fine corallines and algae, while those from the Philippines are concealed 
altogether by stones and sponges.
