Oneirodes alius, a member of the O. schmidti 

 group (Pietsch 1974a), was originally described 

 from three specimens collected by the Alpha Helix 

 in the Halmahera Sea (Seigel and Pietsch 1978). 

 After the description went to press, four additional 

 specimens were sorted out from Alpha Helix sta- 

 tions made in approximately the same localities as 

 the type-material. In all respects, these specimens 

 compare well with the original description.

Material.— LKCM 36031-3, 15.5 mm SL, stn 58; 

 LACM 36057-3 2(65-92 mm SL), stn 93; LACM

The 1975 Southeast Asian Bioluminescence 

 Expedition of the Alpha Helix provided the first 

 representatives of O. schmidti since the capture of 

 the holotype by the Dana in 1929. The new mate- 

 rial compares well with the type-specimen in all 

 characters, except for some minor differences in 

 escal morphology. The species is redescribed below 

 based on the new Alpha Helix material. 



Description. — Escal appendage pattern C (Pietsch 

 1974a, fig. 60C); esca with a large, complex an- 

 terior appendage consisting of a wide, compressed 

 base bearing a relatively short, unpaired and 

 branched filament on posterior margin, two ex- 

 tremely long, distal filaments ( about 16.3 to 17.3% 

 of SL) that bifurcate as many as five times, and a 

 stout, bifurcated, medial filament each branch of 

 which becomes highly branched distally; a pair of 

 filamentous, highly branched, medial appendages 

 less than length of escal bulb; terminal papilla
