66 Mr. Gray's Additio7is to a 



actually found in the Mediterranean, and that the specimen is now iii the 

 possession of a collector at Marseilles. If this account be well founded, 

 it is to be hoped that no long time will elapse before it is given to the 

 public in an authentic shape. It may be worthy of mentioning, that 

 Mr. James Sowerby, who made the drawing of Ocythoe Cranchii as well 

 as that of our specimen, informed me that the position of the tube in the 

 former was exactly opposite to the situation of that in the latter. The 

 tube in our specimen rests on the involuted crest of the shell. In 

 Ocythoe Cranchii it was placed over the wide and opposite part of the 

 shell. A small hole in our shell aftbrded the means of extracting some 

 of the ova for examination without displacing the animal. 



It would be well worthy of inquiry whether the animals found in the 

 shells are male or female ? Most of those captured appear to have been 

 females. 



It may be expected that the author should give a decided opinion on 

 this long agitated question : but those who look for it will be disappointed. 

 In his judgment, much more remains to be known before it is possible to 

 come to a satisfactory conclusion. There is not, perhaps, sufficient evi- 

 dence to convict the subject of our memoir of piracy, but there is quite 

 enough to make us strongly doubt the assertion that " he is his own 

 " industrious shipwright."
