SUMMARY Of CURRENT RESEARCHES RELATING 



the presence of exopodites on the pereiopods and od the second and 

 third maxillipedes. The specimen is, in tact, an Eryonicus in the Mysis 

 Btage of development." A new species of Palinurus, closely allied to 

 /'. vulgaris and P. gilchnsfi. is suggested. All the specimens in the 

 collection were from the bottom except Eryonicus, which is a free- 

 swimming form. 



Palsemons of the Philippine Islands.* — R. P. Cowles deale with 

 the species of Palsemon represented in the lakes and rivers of the 

 Philippines. They are abundant and are much fished for. A full 

 description is given of the external features of a typical Palsemon, and 

 the various species are carefully described, including P. philippinensis 

 sp. n.. and P.jaroensis sp. n. There are excellent illustrative figures. 



New Genus of Terrestrial Isopods.f— W. E. Collinge reports on a 

 small collection of terrestrial Isopods from the Abor Expedition in the 

 foot-hills of the Eastern Himalayas, which includes two new species of 

 Cubaris and a new genus Burmoniscus established for a blind caver- 

 nicolous form, remarkable in having a deep brown coiour. 



New Caprellid.J — A. G. Huntsman describes Mayerellc limicola 

 g. et sp. n. from the Bay of Fundy. Almost every character possessed 

 by the new form is to be found in one or other of the known genera, 

 but the combination it shows is new. The most striking features are 

 the presence of -two joints in each of the first and second pairs of 

 pereiopods, of three joints in the third pair, and of three joints in the 

 mandibular palp (the last with a single bristle). The abdomen of the 

 female has two pairs of spines (perhaps representing appendages), and 

 the abdomen of the male has a pair of rudimentary appendages and a 

 pair of large spines behind these, representing another pair. The 

 habitat was at 5-50 fathoms on muddy and muddy-sand bottoms in the 

 Bay of Fundy. 



Entomostraca of Georgian Bay.§— G. 0. Sars reports on a collection 

 including nine Cladocera (e.g. Daphnia hyalina var. oxycephala G. 0. 

 Sars, Hyalodaphnia retrocurva var. intexta Forbes, and a very small 

 variety of Bosmina longirostris), six Copepods (e.g. Epischura lacustris 

 Forbes, and Diaptomus oregonensis Lilljeb), and one Ostracod 

 {Cyclocypris serena Koch). Sars upholds the species Cyclops thomasi 

 Forbes and 0. edax Forbes. 



Fresh-water Entomostraca of North America. ||— Ada L. Weckel 

 has compiled for students of micro-biology an account of the free- 

 swimming fresh-water Entomostraca of North America, Keys are given
