The specimens from the Gulf of Siam come nearest to the variety delicatula, 
from Riukiu Island, described by Pirssry (loc. cit.). — The boundary line of this 
species is not quite settled and requires to be investigated more closely; REEVE’s 
“fibula” is no doubt also a collective species. Dati (Synopsis of the Lucinacea, 
1901, p. 798) is of opinion that Puitippi’s name divergens must yield place to Conrap’s 
L. bella, which has the priority; it is, however, doubtful if these two species are 
synonymous. In 1834 Conrap (Journal of the Acad. of Natur. Sciences of Phila- 
delphia, VII, p. 254) described Lucina bella from specimens collected by Mr. Tu. 
Nurracy “in muddy marshes near Sta. Diego” (Upper California) ;’ but Dat thinks 
that there must have been a mistake, and that the specimens were “probably” 
collected at the Sandwich Islands. Before rejecting Puitiprr’s “divergens,”’ all the 
forms in question should be thoroughly investigated.
