20 THE VOYAGE OF H.M.S. CHALLENGER. 



adult Stomatopods fall into their proper places, it furnishes very satisfactory proof of 

 the relationship between the larvae and their adults. 



Faxon has reared a Squilla empnsa from an Alima larva. The Challenger collections 

 show that the larva of Lysiosquilla maculata is one of the short-spined Lysioerichthi ; I 

 have reared Lysiosquilla (Coronis) excavatrix, one of the more primitive Lysiosquilla}, 

 from a long-spined Lysioeiichthus. Glaus has figured a series which shows beyond 

 question that at least one species of Pseuderichthus becomes a Pseudosquilla, and the 

 Challenger collections furnish ecpally good proof that the Chiragra group of Gonodactyli 

 come from Gonerichthus larvae, and I therefore believe that we may very safely assume 

 that all the Lysiocrichthus larvae are young Lysiosquilla^, all the Alima larvae young 

 Squills, Alimerichthus one of the lower Squillw or Oiloridellai, all the Gonerichthi 

 young Gonodactyli, Erichthalima very probably a young Coronida, and all the 

 Pseuderichthi very probably young Pseudosquillse. The evidence for this conclusion can 

 be much better estimated after the examination of the special descriptions which follow.
