ARCTURUS BREVISPINIS, new 



species. 



This species ditfers from 

 Arcturus longisjnnus Bene- 

 dict in having all the spines 

 quite short, those of the last 

 three thoracic segments and 

 the first two abdominal seg- 

 ments being almost rudi- 

 mentary. The terminal ab- 

 dominal segment in all these 

 specimens is longer than in 

 A. longispiniis. The body is 

 covered with small, pointed 

 tubercles. The first antennaj 

 extend the length of the last 

 article bej^ond the second ar- 

 ticle of the second antennae. 

 The last article of the first 

 antennae is about three times 

 longer than the third article. 



About nine specimens were 

 collected at station 4784, on
