SOHIZOPODA. 21 



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

 MetanaupUi and Calyptopis larvse, and two Furcilias. 



The MetanaupUi and Calyptopis larvse 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 larvse 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. 156° 19' 30" E., 22. 11. 01, seventeen Calyptopis and fifty 

 Furcilia larvae. 



The Calyptopis larvse belong to the same species as in the preceding lot. 



The Furcilia larvse 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 MetanaupUi, Calyptopis, 

 and Furcilia larvse. 



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 the 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 larvse. 



Lat. 63° 4' 24" S., long. 175° 47' 57" E., 1. 1. 02 ; numerous Furcilia larvse 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 MetanaupUi and Calyptopis larvse, the 

 largest of which measured 2 mm. 



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

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



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

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

 Thysanoessa macrura. 



Order MYSIDACEA. 



Family PETALOPHTHALMIDiE, Czerniavsky. 



Fetalophthalmidse, CzerniaTOky, 1882. 

 Feialophthalmidse, Holt and Tattersall, 1906 (2). 



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

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

 a quarter of a century previously. Czerniavsky, however, had no specimens of any of
