The researches of Conn (65), which were conducted on Thalassema 
mellita , n. sp., lead him to agree with those who regard the Gephyrea as 
modified Annelids. He describes the developmental history very fully. 
Rietsch (G7), who has investigated the structure of Thalassema neptuni, 
Echiurus pallasi , and two species of Bonellia , describes the systems of 
organs in great detail. 
Schauinsland (68) points out the great differences which obtain be- 
tween the excretory organs and genital products of Priapulidce and other 
Gephyrea. 
Sluiter (69, p. 516) gives a list of the species described by him from 
the Malay Archipelago in 1881-85 ; he describes as new : — 
Sipunculus billitonensis , p. 487 ; 
Aspidosiphon tenuis , p. 491, A. levis , p. 493, A. rarus , p. 495, A. 
exilis , p. 497 ; 
Phymosoma spengeli } p. 498, P. duplici-granulatum, p. 501 , P. poaron, 
p. 505, P. microdonto, p. 506, P. lacteum, p. 507, P. diaphanes, p. 509, P. 
maculatum, p. 511 ; 
Phascolosoma abnormis, p. 513.
