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

 \fftanauj>lii and Ctilyptoj>i larvae, and two Furcilias. 



The Mttanauplii and Calyptopis larvae arc characterised by the presence of a 

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

 forma the hood over the eyes, appears to have ita margin quite smooth. In the 

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

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

 Calyptopis larva measures 4 mm. in length. 



Lat 56 31' &, long. 156 19' 30" E, 22. 11. 01, seventeen Calyptopu and fifty 

 Furcilia larvae. 



The Calyptopis larvae belong to the same species as in the preceding lot 



The Furcilia larva) measure from 2'5 to 4 mm. They present no features of 

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

 Calyptopis larvie 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 Metanaujtlii, Calyptopi*, 

 and Furcilia larvae. 



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 Pwrdlin 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 larva) 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 Metanauplii and Calyptopis larvae, 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 superla. 



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

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

 T/iystimnissa macrura.

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
