Remarks. It is uncertain if Sph. monolinus Heller is 

 identical with the species of Dana. 



23. Spherillo aucklandicus. 



Spherillo monolinus Heller, Novara Exp. 135. 

 Armadillo Aucklandicus B.-L. Crust. Is. Terr. 40. 

 Patria: Auckland. (Novara Exp.). 



Also perhaps belongs here: 



24. Spherillo speciosus. 



Armadillo speciosus Dana, Expl. Exp. Crust. 718. Tb. 47. f. 2 a— d. 



Patria: New Zealand, »in the mount Taiammai near 

 Bay of Islands*. (Expl. Exp.). 



Remarks. I do not believe this species is identical 

 with J.rw. speciosus Chilt. Tr. Lin. soc. Lend. 1901 p. 146. 

 I have registered this last species later (Nr. 32). I agree 

 with Chilton in his opinion, that it is probable, that 

 Dana has overlooked the exopodit of the uropods. He 

 cannot mean it to be minute or rudimentary, when he says 

 »ramo obsoleto«, and has brought this character to separate 

 the two genera Armadillo and Spherillo; but on the other 

 side I have never seen a species of Armadillo or Spherillo 

 completely wanting the exopodit. 



One term in the description of Dana, »The last seg- 

 ment (o: telsum) has a faint suture across it, which appears 

 to show* the outline of a seventh normal segment^ shall 

 Certainly lead to find out the true species of Dana. 



I insert also here: 



25. Spherillo vitiensis. 



Spherillo vitiensis Dana, Expl. Exp. Crust. 721. Tb. 47. f. 4a— d. 



Patria: >>In the island Vanua Levu« (Expl. Exp.). 



Remarks. I think this species will perhaps be recog- 

 nised by the description of Dana, of which I extract the 

 following: 



»Head with the eyes on the posterior angles«.
