276 Part III.—Nineteenth Annual Report 
Nannastacus unguiculata, Speuce Bate. 
Male and female specimens of this curious species were captured by 
the steam trawler “St. Audrew” in Lerwick Bay, Shetland, by means 
of a surface tow-net put overboard for four hours while the vessel was 
at anchor. A single male specimen of Vaunthompsonia cristata was 
also obtained in this gathering. Nannastacus unguiculata was taken 
at Shetland in 1863 by the Rev. A. M. Norman; it was also taken in 
Lerwick Bay in 1867 by David Robertson by means of a surface tow- 
net,* and in connection with this it is interesting to note, from the point 
of view of the distribution of the species, that though Vauwnthompsonia 
cristata and Nannastacus unguiculata are both members of the Shetland 
marine fauna, and the latter especially not uncommon, yet Professor G. 
O. Sars in his work on the Norwegian species belonging to the 
Sympoda, recently published, does not include either of the forms 
named. 
CAMPYLASPIDA. 
Campylaspis rubicunda (Lilljeborg). 
This species was obtained in gatherings collected by the “St. 
Andrew ” off Fair Island on the 12th, 16th, and 19th of October at various 
depths from 60 to over 80 fathoms. 
Campylaspis costata, G. O. Sars, 
This species was obtained in the same gatherings with the last, and 
was, if anything, more frequeut. It also occurred in a gathering from 
Loch Aber (upper end of Loch Linnhe) collected by the ‘‘ Garland ” in 
82 fathoms on April 2nd. 
Sub-order SCHIZOPODA. 
Mysip&. 
Mysidopsis didelphys { Norman), 
This Schizopod has been obtained during the past year by the 
“Garland” off Aberdeen, and by the “St. Andrew” off the Fair Island. 
It was collected off Fair Island in 60 to 70 fathoms on the 19th of 
October, and off Aberdeen in 60 fathoms on the 25th of the same month. 
The Rev. A. M. Norman obtained it in 40 to 50 fathoms, five to eight 
miles east of Balta, Shetland.t 
Heteromysis formosa, S. I. Smith. 
Hitherto the Firth of Forth is the only Scottish locality whence 
this Schizopod has been recorded.£ It is one of the many species which 
have been added to the Scottish marine fauna as one of the results of the 
investigations carried on under the direction and by the encouragement 
of the Fishery Board for Scotland. 1 have now to record Heteromysis 
formosa for the first time for Loch Fyne and the Moray Firth. It 
occurred with some other rare things in material dredged by the 
“Garland” at Tarbert Bank, Lower Loch Fyne, in about 20 fathoms, on
