NO. 4 schmitt: stomatopods 171 



These several species also seem to have a more pronouncedly subcylin- 

 drical body as compared vi^ith the group first listed, in which, indeed, some 

 have very much flattened, depressed bodies. 



Pseudosquilla empusa has uropods which place it in the B section of 

 Kemp's key, and so may have 2 joints to the shorter ramus of the posterior 

 thoracic limbs, but this point needs to be verified. Komai (op. cit.) is the 

 first to have seen any specimens of this rare species since originally 

 described by de Haan, but he fails to describe the thoracic limbs other 

 than the raptorial one. His color figure regrettably does not clearly show 

 the structure of the shorter ramus of the 6th to 8th pair. 



Although the shorter ramus of the 6th, 7th, and 8th thoracic limbs 

 of Pseudosquilla may be composed of one or two segments, in Lysiosquilla 

 the number of segments is always 2, as it is also in Corontda and Gono- 

 dactylus; in Hemisquilla there is but one ; in Squilla "the shorter ramus 

 of the last three thoracic appendages is unjointed, or with an imperfect 

 suture separating short basal and long linear distal parts" (Kemp). 



In all the species examined the mandibular palp was composed of 3 

 segments. 



The Lysiosquilla plumata and maiaguesensis of Bigelow*^ are at best 

 immature forms, very small, which unfortunately at some time or other 

 must have dried out completely. They are now preserved in alcohol. The 

 telson of each has an evident median carina and has no submedian 

 spinules ; the uropods are of types admissible to the genus Pseudosquilla, 

 that of maiaguesensis very clearly so. However, I find no trace of a 

 mandibular palp in either species; the shorter ramus of the posterior 

 thoracic limbs is somewhat broadened, narrow bladelike rather than 

 merely linear and seems, moreover, to consist of but the one joint. 



As a result of the foregoing remarks and of the species here assigned 

 to the genus, the veiy excellent generic definition given by Kemp for 

 Pseudosquilla needs to be emended : in the first place, the number of teeth 

 on the raptorial dactylus can no longer be limited to 3 or 4, including 

 the terminal one. It should be merely stated (as with Chloridella, or 

 Squilla) that the raptorial dactylus is toothed. Then, the shorter ramus 

 of the last 3 thoracic limbs is composed of one or two segments. Finally, 

 the basal or ventral process of the uropods may consist of only 2 spines, 

 of which either the inner or outer may be the longer,"*^ or of 2 spines with

46 Kemp had it that the inner spine was the longer in those Pseudosquillas in 

 which the ventral process of the uropod consisted of but 2 well-formed spines. In 

 P. oculata the outer spine is much the longer.
