PLYING SPIDERS. 319 



" A second species,, which we also obtained in the 

 Pacific, resembled the above in size and form, but its two 

 long tentacles were furnished at their extremities with 

 rows of suckers (acetabula), instead of horny, hooked 

 appendages. The prevailing colours of this species are 

 silver- white and steel-blue, spread with red spots and 

 tints of violet and purple, a brilliant and very beautiful 

 spot of emerald green being placed immediately above 

 each eye. We noticed examples of this family of 

 cephalods from the Equator to lats. 34 N. and 160 S., 

 Pacific Ocean.-" 



In this interesting account there is one decided 

 error, namely, in thinking the posterior fins or flaps 

 at either side of the sharply-pointed tail to be the 

 instrument of locomotion. This is not the case, for 

 the animal always flies tail foremost, and must in that 

 case turn round in the air, which would decrease its 

 impetus. The real organ of propulsion is the siphon 

 which has just been described. 



The species which Mr. Bennett first mentioned 

 belonged to the genus Onychoteuthis, or Hooked Cuttle, 

 so called from the hooks upon the ends of the 

 tentacles. 



FLYING SPIDERS. 



The last of the air trespassers for which I have 

 space are those little spiders which are known as 

 Gossamer, and which float so plentifully in the air 

 that they sometimes become very annoying to per- 

 sons who are out in the open air.
