Supplement 



By M.E. Vinogradov and T.N. Semenova 

 (translated by D. Siegel-Causey) 



It has been ten years since the pubHcation of this book in Russia. Since 

 this time, there have been many presentations about the hyperiid fauna 

 in the World Ocean, and some of these have made definitive changes to 

 our knowledge. A few new species have been added, some other species 

 have been better described and with new generic affinities. New findings 

 of a series of species have introduced new information concerning their 

 areas of distribution. Further, some hyperiids known to inhabit only one 

 ocean now have been found in two or three other oceans, for example: 

 Pegohyperia princeps, Vibiliodes alberti, Vibilia alberti, Vibilia caeca, 

 Megalanceola stephensi, Hyperia bowmani. For a few of the species, 

 information on the depths of collection were changed significantly. All 

 of these changes made it necessary to provide a short supplement to the 

 original text, which will make this translation more contemporary. 



I. New species of Hyperiidea described since 1982. 



1. Hyperia curticephala Vinogradov and Semenova, 1985 (Figure 1) 



Sexually mature males, 11-12 mm; females, 10 mm. 



H. curticephala is distinguished from other species in Hyperia by 

 its particularly long head. By many other characters, it is very near 

 to H. leptura and to a lesser extent to H. bowmani, although one can 

 distinguish one from the other. From H. leptura, the difference is by the 

 presence of two apical spines on the medial lamina of the maxilliped, 

 strong distal widening of article 5 of pereopods I and II, greater length 

 of the distal part of article 5 on pereopod II, pereopoda III and IV are 

 weakly equipped with spines, as are the edges of the epimere I and 

 the apex of the telson. From H. bowmani, it differs by its smaller size, 

 coloration, the relative elongation of articles on pereopoda III and IV by 

 4 to 5 times, the distally wider article 5 on pereopod II, very short claws 

 on pereopoda III and IV, and practically no armament on pereopoda 

 V and VI, which on H. bowmani are covered by dense rows of long 

 submarginal or marginal bristles. For convenience, a comparison of these 

 three species is given in Table 1. 



This species was collected mostly in association with the spherome- 

 dusid Chrysaora plocamia in the Pacific Ocean in the coastal waters of
