FAMILY III. PTYCHODERID& SPENGEL, 1893. 
Genus I. Glossobalanus Spengel, 1901. 
* 2. Balanoglossus Delle Chiaje, 1929. 
* 3. Ptychodera Eschscholtz, 1825. 
The classification adopted by the author in his monograph was 
unfortunate in that it conflicted at several points with established 
rules of nomenclature. For example, the type species of Ptychodera, 
P. flava Eschscholtz, 1825, would have been removed by Spengel to 
new genus, Tauroglossus. Delle Chiaje’s well-known species, 
Balanoglossus clavigerus, was likewise deprived of its original generic 
name and placed in the suggested genus Tauroglossus. 
Both these pioneer species are now restored to their rightful 
places as types of the genera to which they were originally assigned. 
Thislatest scheme of classification of the Enteropneusta undoubtedly 
corresponds nearer to the actual relationship of the species than any 
other that has been proposed. 
As the author remarks, however, the three genera constituting the 
Harrimaniidz are certainly considerably less closely related than are 
those constituting the other two families. 
Dolichoglossus in particular, I would remark, is: much less close of 
kin to the other genera of the family than these genera are to each 
other. Wm. E. RITTER. 
Hymenoptera Parasitica Hawaiiensis. — The part of the Fauna 
flawaiiensis (Vol. I, Part III) dealing with the parasitic Hymenoptera 
has just come to hand. It is written by Mr. W. H. Ashmead, who 
has prefaced to the purely descriptive part some very interesting 
remarks on the Hymenoptera of the Hawaiian group. Of the 128 
parasitica enumerated, no less than 87 are described as new; these 
do not include any which cannot be referred to known families, but 
eleven genera appear to be endemic. Several of the previously 
known species are easily recognized as introductions from other parts 
of the world. Mr. Ashmead suggests that the list as given must 
quite inadequately represent the actual fauna, *since many of the 
common parasitic families, which must surely occur, are entirely 
unrepresented." Since writing these words, Mr. Ashmead has him- 
self visited the islands, and no doubt he will shortly publish the 
results of his own collecting; but it may be pointed out that the 
cond'tion observed is characteristic of oceanic islands in general, 
and of the Hawaiian Islands in particular, as may be seen by refer- 
ence to Wallace's Zs/and Life, second edition, Chapter XV. Hence,
