132 VERANY AND VOGT ON THE HECTOCOTYLI 



taken near land by means of drag-nets. Professor Bellardi of 

 Turin, who was at Nice in April of this year, assured us that 

 having been present at the raising of the Madrague nets*, he saw 

 one of these Octopods attached to a dead Salpa. The Octopus 

 evidently approaches the shore at the pairing season, and it is 

 to this cause, as well as to the arrangements we made, that we 

 owe the capture of twenty males and two females which were 

 all taken last April. All the specimens have been brought to us 

 living : a single male had lost its hectocotyliform arm ; all the 

 others presented this arm either wholly developed or still in- 

 cluded within its vesicle. The male by itself has been described 

 and figured since 1846 in the Acts of the Royal Academy of 

 Sciences of Turin, by one of us, and later in the Monographic 

 des Cephalopcdes de la M edit err anee which has just appeared. 

 The female has perhaps been described by M. Risso under the 

 name of Octopus tuberculatus, but the short phrase applied to 

 this new species is so vague and diffuse, that it may equally 

 relate to the Tremoctopus catenulatus. M. Risso having left no 

 specimen marked by himself by which it might be decided to 

 which of the two species his description refers, we must retain 

 the name given by one of us in 1836; and so much the more 

 since M. d'Orbigny has already designated Octopus tuberculatus, 

 another species of Octopus previously described by M. de 

 Blainville. 



M. d'Orbigny does not mention our T. Carena in his Mono- 

 graph upon the Cephalopoda. It is very remarkable that this 

 species, which this year was so frequently taken, and which be- 

 sides does not appear to be very rare, should have escaped Delle 

 Chiaje, whp has enriched science with so many new species ; 

 Prof. Philippi,who has so carefully explored Sicily; M. Cantraine, 

 who has traversed a large portion of the Mediterranean ; as well 

 as MM. Kolliker, Riippell, Krohn, and H. M'uller, who have 

 specially occupied themselves with the Cephalopoda in Sicily. 

 However, we have reason to believe that the Octopus granulosus, 

 upon which Laurillard found the Hectocotyli which were de- 

 scribed by Cuvier, is the female of the species with which we are 

 engaged.

 St. Hospice, a league from Nice.
