LIST OF THE HOLOTHURIANS IN THE COLLECTION 

 OF THE LEYDEN MUSEUM 



DRAWN UP BY 



Prof. Dr. HUBERT LÜDWIG 



in Giessen. 



The collection of Holothurians in the Leyden Museum 

 was sent over to me with the request that I would sub- 

 ject them to a systematic revision. I undertook this task 

 in the hope of being able at the same time by the aid of 

 this material to make a step in advance with respect to 

 their anatomy. Unfortunately in nearly all the specimens 

 the intestines were so insufficiently preserved , that I was 

 forced to limit myself to the identification of the species. 

 This, however, was not superfluous, as the majority of the 

 specimens were incorrectly named and as certain localities 

 are not without interest for the question of geographical 

 distribution. The collection of Holothurians in the Leyden 

 Museum contains a total of 52 species (two of them being 

 new) , most of which were obtained from the Oriental and 

 Moluccan regions.
