other. The specimens examined by Hérouaed belong to M. verrilU, 

 so that his remarks must concern this spedes. According to his 

 system, M. intestinalis and M. verrilli would belong to different 

 genera ! But such a classification is evidently unreasonable, as there 

 can be no doubt about the close affinity between these two species. 

 Nor it is hkely that any other author will recognize the genus Al- 

 lantis. If the differense in size among of the tentacles, as men- 

 tioned by Hérouaed, is always to be found in M. verrilli, which 

 appears to me doubtful; tlien this would of course be -a definite 

 proof for the correctness of my opinion, expressed both in 1896 

 and on page 6 of the present treatise, that this species ought to be 

 distinguished from M. intestinalis. 



Later on I hope to have an opportunity of referring to Hérou- 

 aed 's book, which appears to give occasion for still further criticism.
