plain of Arctic Ocean (about 69" 40' N., Notostraca (Apodidae) means "pond- 



141 W.) ; isolated pond off Old Crow ray"; but I think it better to use a popu- 



I^iver. lar English name for them which indicates 



Both of these species have been already the class of animals to which they belong, 



mentioned in this article. 



Note. I have been unable to find any 

 popular, English names for Notostraca and 

 Conchostraca, and am therefore in these 

 articlea proposing the names of "tadpole- 

 shrimps" and "clam-shrimps" for them. 

 To distinguish the "clam-shrimps" from 

 the Ostracoda I propose for the latter the 

 name of "mussel-shrimps", a translation 

 of the popular, Danish name for the Os- 

 tracoda. The difference in the shape of 

 the shell between the Conchostraca and the 

 Ostracoda is thus indicated in these popu- 

 lar names. The popular Danish name for 



A-E: Eubranchipus gelidus Hay; P: Lepidurus 

 couesii Pack; G-H: Limnetis gouldii Baiid. 

 Above letters explained: fo: frontal organ; 

 ai first pair of antennae; a^ (cl) : 2ncl pair 

 of antennae (or claspers); ne: nauplius- 

 eye; pe: paired eyes; fi: filaments of 1st 

 pair of feet; so: bodysegments (somites); 

 fl: foliaceous legs; ca: carapace (or shell); 

 bk: beak of head; in: intestine; pr: pro- 

 cesses from somites; eg: eggsack with eggs; 

 ge: male genitalia; ad: abdomen; te: tel- 

 son; cp: cercopods. (A and E, after Pearse; 

 F-H, after Packard; B-D, Originals.) A, 

 C, E, F2, G are lateral views; D and Fl: 

 dorsal views; B: clasper from inside; H: 

 front view of head.
