The Schizopoda collected by the Maia and Puritan in the Mediterranean. 123 
in 9 of the Maia hauls and 28 of those of the Puritan. The largest 
specimen measured 15 mm in length. 
This species was new to the fauna of the Mediterranean at the 
time of its capture by the Maia. 
4. Meganyctiphanes norvegica (M. Sars). 
Nyctiplianes norvegica (pars), Lo Bianco (1901, 1903 and 1904). 
Meganyctijphanes norvegica^ Holt & Tattersall (1905 and 
1906), Masi (1906). 
Euphcmsia intermedia, Riggio (1905). 
This species occurred sparingly in 4 gatherings from the Maia 
and in 10 from the Puritan. The largest specimen measured 33 mm. 
Previous to the cruises of the Maia and Puritan this species 
had not been recorded from the Mediterranean. It has since been 
noted from there by Riggio as Euphausia intermedia^ a name corrected 
to M. norvegica at the end of bis paper, and as abundant off the 
island of Giglio by Masi. Holt and Tattersall (1906) bave already 
called attention to the fact that the drawing in one of Lo Bianco's 
memoirs (1904) attributed to this species, has, in fact, no connection 
with M. norvegica at ali. 
5. NyctipJianes couchii (Bell). 
N. norvegica (pars). Lo Bianco (1903). 
This species is evidently not common in the Mediterranean since 
4 specimens were ali that were found in the collections of both the 
Ma ia and Puritan. It seems probable, however, that both expeditions 
were fishing beyond the true zone of N. couchii which is apparently 
an inshore rather than an Oceanie form and is rarely found in depths 
exceeding 100 fathoms. 
Lo Bianco included this species in bis records of M. norvegica. 
6. Thysanopoäa aequalis Hansen. 
T. ohtusifrons, Lo Bianco (1901 and 1903; nec G. 0. Sars, 
1885). 
T. microphthalma , Lo Bianco (1903; nec G. 0. Sars, 1885). 
T. aequalis, Hansen (1905b). 
I refer all the Thysanopoda in this material to T. aequalis 
Hansen, a species but very recently defined. It is very closely allied 
to T. ohtusifrons G. 0. Sars, with which Lo Bianco has confused it, 
but is distinguished by the shape of the lobe on the antennular
