in proportion to their propodi, but their form is quite different; the dactyli are namely of a 

 much less slender shape, only 5- or 6-times as long as wide at base, the 

 terminal claw (stylopodite) measures one-third the entire length of the joint and the accessory 

 claw is nearly half as long as the terminal. The measurements in millimeters of the three 

 Barcelona specimens and that from Naples are the following:

N° 1 male, N ,J 2 and 3 ova-bearing 



females of Parapandalus pristis (Risso) from off 

 Barcelona. When measuring the 4 th leg of the male, the carpus and propodus were broken, so 

 that it proved impossible to measure them exactly. When comparing these measurements with 

 those of Parap. serratifrons, the close resemblance will strike ; of the female (N° 3) the propodus 

 of the 3 rd leg is abnormally short, while the propodus of the 5 th is shorter than the carpus. 

 N" 4 Gulf of Naples. 



Pandalus escatilis Stimps. from off Madeira seems to be likewise a closely related form, 

 but to differ from Parap. serratifrons Borr. by the endopodite of the external maxillipeds 

 resembling that of Pandalus annulicornis Leach : in the latter species indeed the penultimate 

 joint of the external maxillipeds is not longer, but shorter than the terminal (Vide W. T. 

 Calman, Annals Mag. Nat. History. Ser. 7, Vol. III, 1899, PI. II, fig. ld).

Dorodotes Bate. 



The genus Dorodotes Bate is still only represented by one species, a rare form observed 

 in the Indian Archipelago and in the Bay of Bengal, where it occurs at the great depths 

 varying between 1050 and 1530 fathoms.
