LXVTI. — The Squirrels described as Sciurus steerii from 

 Balabac and Palawan. By Oldfield Thomas. 



In 1876* Dr. Giinther described and figured two squirrels 

 collected by Dr. Steere on the islands of Balabac and Palawan 



as Sciurus steerii, he being under the impression that they 

 represented but a single species inhabiting the two islands. 

 Since then, however, a number of these squirrels have come 

 to Europe, and all those from Balabac prove to be precisely 

 identical with Dr. Gunther's No. 1, from that island, while 

 all those from Palawan, although considerably more variable, 

 inter se, than the Balabac ones, agree in differing from the 

 latter by their browner, less rufous colour, their greyish sides, 

 and black-tipped tail, as described by Dr. Giinther under 2. 

 In belly-colour, however, they may be white or cither 

 partially or wholly rufous. 



This being the case, it is evident that the squirrels from 

 the two islands should be considered as distinct species, and 

 I would propose to restrict the name S. steerii to Dr. Gunther's 

 No. 1, the foremost figure on his plate, with its type 

 B.M. no. 70. 10. 4. 4, and to assign the name 8. juvencus to 

 the Palawan species, described by Dr. Giinther under No. 2 

 and drawn in the background of his plate, its type being 

 4UI.no. 70. 10. 4. 3. 



With regard to the variation in the belly-colour of S. ju- 

 vencus it is to be noticed that the greatest extremes, all white 

 and all red, are shown by specimens from the same place, 

 Puerto Princesa. 



LXVIII. — Note on the Copepod Genus Oithona. By G. P. 



FARRAN, Department of Agriculture and Technical Instruc- 

 tion, Fisheries Branch, Dublin. 



In going through some collections of Copepoda taken by the 

 Department of Agriculture's cruiser ' Helga ' off the \V. and 

 S.W. coasts of Ireland I have noticed the presence of two 

 species of the genus Oithona which at first sight appear to be 

 (>. plumifera and (J. secigera, but on a closer examination are 

 seen to possess some minute points of difference from those 

 species. As the local distribution of the members of this
