the Trondhjem Fiord. 483 



common British species, and it reaches the Mediterranean, 

 whence I have received specimens from Delia Valle, who 

 records it under this name. 



85. Harpinia pectinata, G. 0. Sars. 

 Rodberg, 250-300 fathoms. 



86. Harpinia truncata, G. O. Sars. 



Five specimens, Rodberg, 250-300 fathoms. Sars's 

 description was drawn up from two specimens also taken in 

 the Trondhjem Fiord, which is as yet the only recorded 

 habitat. 



87. TJarjjinia crenulata, Boeck. 



88. Harpinia Icevis, G. O. Sars. 



Two examples, Trondhjem, in 20-40 fathoms. 



89. Ampelisca typica, Bate. 



=A. Gaimardi, B. & W. (nee Kroyer). 



Trondhjem, between Monkholmen and the land. Delia 

 Valle's description and figures clearly show that the Araneops 

 hrevicornis, A. Costa, 1853, and Ampelisca laevigata, Lilljeborg, 

 1855, are the same species ; and this I have confirmed by 

 comparison of specimens, and the latter specific name must 

 therefore give way to the former, of which another synonym 

 is A. BeUiana, Bate. But when Delia Valle proceeds further 

 to make Tetromatus typicus, Bate, and A. gibha^ G. O. Sars, 

 also synonyms of A. brevicornis^ I am at a loss to understand 

 on what grounds he has arrived at such a conclusion. 



90. Amp)elisca assimilis, Boeck. 



Trondhjem, two or three specimens in shallow water. 



91. Ampelisca gibba J G. O. Sars. 

 Rodberg, 150-300 fathoms, frequent. 



92. Ampelisca macrocephala, Lilljeborg. 

 Trondhjem, 20-40 fathoms j also at Rodberg. 



93. Ampelisca odontoplax, G. O. Sars. 

 Numerous specimens, Rodberg, 100-300 fathoms.
