SCHIZOPODA. 21 



Lat. 57° 25' 30" S., long. 151° 45' R, 21. 11. 01, uumeroiis Euphausian 

 Metanauplii and Calyptojns larvae, and two Furcilias. 



The Metanauplii and Cah/ptopift larvpe are characterised by the presence of a 

 short blunt posterior median spine on the carapace. The front part of the latter, which 

 forms the hood over the eyes, appears to have its margin quite smooth. In the 

 majority of the Calyptopis larvae a small spine on the lateral margins of the carapace 

 is clearly present. The apex of the telson is very slightly emarginate. The largest 

 Calyptopis larva measures 4 mm. in length. 



Lat. 56° 31' S., long. 15G° 19' 30" E., 22. 11. 01, seventeen Calyptopis and fifty 

 Furcilia larvtx;. 



The Calyptopis lar\';c belong t<j the same species as in the preceding lot. 



The Furcilia larvae measure from 2"5 to 4 mm. They present no features of 

 note, but from their size they probably belong to a smaller species of adult than the 

 Calyptopis larvse which accompany them. All present a lateral spine on the carapace, 

 and the rostrum is in the form of an acutely produced triangular plate. 



Lat. 54° 1' S., long. 170° 49' E., 27. 12. 01, numerous Metanauplii, Calyptopis, 

 and Furcilia larvaj. 



All these are apparently stages of one species. The largest Calyptopis larva 

 measures 3 mm. and is without a posterior median spine on the carapace. The 

 anterior margin of the hood is smooth ; there is a lateral spine on tlie carapace, and the 

 apex of the telson is very lightly convex. The largest Furcilia measures 4 • 5 mm. 



Lat. 61° 13' 30" S., long. 173° 33' E., 31. 12. 01, one Furcilia larva, 5 mm., 

 apparently the same species as the following larvae. 



Lat. 63° 4' 24" S., long. 175° 47' 57" E., 1. 1. 02 ; numerous Furcilia larvaj from 

 4 mm. to 5 '25 mm. in length, and apparently the same species as the preceding larva. 



Wood Bay, 22. 2. 04, numerous small Metanaup>lii and Calyptopis larvte, the 

 largest of which measured 2 mm. 



Lat. 70° 29' 27" S., long. 168° 51' 46" E., 26. 2. 04, one late Cyrtopia larva, 

 9 mm. in length, which, from its size, is probably Euphausia superha. 



Lat. 49° 40' S., long. 112° 18' 30" W., 12. 6. 04; forty-eight larvas, from 

 Calyptopis stage to post-larval form, measuring 5 mm., and probably the larvae of 

 Thysanoessa macrura. 



Order MYSIDACEA. 

 Family PETALOPHTHALMIDiE, Czerniavsky. 



Feialophthalmidse, Czerniavsky, 1882. 

 Feialophthalmidse, Holt aud Tattersall, 190G (2). 



When defining this family Holt and Tattersall, 1906 (2), overlooked the fact that 

 it had been estaldished and defined, albeit rather incompletely, by Czerniavsky (1882) 

 a (|uarter of a century previously. Czerniavsky, however, had no specimens of any of
