capacity as Dean of the College of Science, and ia other official relations, many responsibilities 

 devolved upon Professor Mitsukuki, so that he could devote only a limited portion of his time 

 to his favorite study. To this he often alluded with regret. 



After his death, on September I7th. 1909, all the notes, manuscripts, drawings, photographs 

 and preparations left by Lim relative to the subject, v/ere taken charge of by the undersigned, 

 to whom Professor Mitsukuei had eatrusted their publication as far as should be found practic- 

 able. In fulfilling this sad duty the elitor has been fortunate in securing, as co-editor, Mr. H. 

 Ohshima, Rlgakushi, a student of Professor Mitsukuri's who, at the editor's suggestion, has taken 

 up the Holothurioidea as the subject of his sjiecial study. 



The two editors found that the notes and manuscripts related chiefly to the actinopodous 

 Holothurioidea and were, for the greater part, nearly or quite ready for publication. In pre- 

 paring them for the press, a small part, consisting of apparently provisional statements, or 

 referring to doubtful furrus, have been omitted. All the notes and figures that remain unpublished 

 will be utilized by Mr. Ohshima. in his rese.xrches, and sj far as practic.xble will be incorporated 

 into his future publication with due acknowledgement of the source. 



In bringing this monograph to its present f )rm. credit is due to Mr. Ohshim.v for the 

 laborious work of arranging the minusaript and th3 plates, and of making for the text careful 

 drawings from the original s'œtche^ and photographs. 



Had Professor Mitsukubi lived to finish this work himself, it is easy to suppose that it 

 would have assumed a form greatly different from, and incomparably more worthy than, that 

 in which it is now presented. — Prof. I. Ijima.
