•I7(i TRAPEZIA RT'FOPUNCTATA. 



8. Trapezia rufopunciata (Rupp.) Heller (nee Herbst). 

 Heller, 1. c. pag. 350. 



Four fine specimens of this species (2 cT and 2 9) were 

 collected in the sea of Djeddah. This species may at first 

 sight be distinguished by its colour, the distinctly de- 

 veloped frontal teeth , Avhicli are very similar to those of 

 Trap, cymodoce Herbst, and by the distinct acute tooth 

 on the lateral margin of the carapace. I have found in 

 the Museum a fine Trapezia , presented by Mr. Milne 

 Edwards and collected in the Nukahiwa seas ; this specimen 

 is labelled as JV;ap. rufopunctata Herbst and I believe 

 it to be this species. But I think Trap, rufopunctata Herbst 

 to be another than Trap, rufopunctata (Rupp.) Heller; to 

 the latter a new name should be given. In the species , 

 described by Herbst (Krabbe und Krebse , tab. 47) the four 

 teeth of the front are all very acute, acuminate and sepa- 

 rated by deep incisions , the external teeth are a little 

 higher than the median teeth , directed outward with their 

 points and with an almost vertical external lateral margin ; 

 the internal angles of the orbits are however also rounded 

 and are less prominent than the frontal teeth. — Mr. Hil- 

 gendorf is wrong in believing these two species to be iden- 

 tical. — Trap, rufopunctata Rupp. (Heller) differs fi'om 

 Trap, cymodoce Herbst moreover by its hands being quite 

 smooth and the upper margin of these hands not being 

 hairy on its outer surface. 



Breadth of carapace of an adult female specimen of 

 Trap, rufopunctata (Rupp.) Heller, provided with eggs, 

 17 mm., whereas the Nukahiwa specimen of the true ?vy/o- 

 punctata of Herbst has a carapace of 25 mm. broad.

Two fine female specimens of this sharply characteri/ed 

 species were collected , which agree iu all points with the
