APPENDIX F.— No. VIII. 



ON A CRANGON, SOME SCHIZOPODA, AND GUiMACEA NEW 

 TO OR RARE IN THE BRITISH SEAS. By the Rev. Canon 

 A. M. NoKMAN, M.A., D.C.L., F.L.S. 



The Scotch Fishery Board have sent me for examination some of the 

 higher Crustacea which have been met with during the past year. Among 

 these are many species of interest, and these are recorded in the following 

 notes. With few exceptions the several forms are now first published as 

 members of our Fauna, although some of them have been long known to 

 myself. Mr Brook and Mr Scott must be congratulated on the success 

 which has brought these species to light, and their discovery will, I trust, 

 lead other naturalists to realise how much remains to be done among the 

 great class of Crustacea in our seas ; and that careful investigation will be 

 amply rewarded even among the higher orders ; but no real progress can 

 be made with respect to the food of fishes until investigators are familiar 

 with those smaller Crustacea which constitute so large a portion of 

 that food. As an instance of this I may mention that Dr Baird, many 

 years ago, published an interesting paper on the food of the vendace. 

 No author at that time was more competent to undertake the task, and 

 two of the Entomostraca in the stomachs were new to science, one of which, 

 Bosmina coregoni., has not as yet been met with elsewhere in our islands 

 than in Lochmaben. Yet when I repeated these investigations three 

 years ago, I found that while the vendace fed on those species recorded 

 by Dr Baird, a large portion, perhaps in bulk the largest portion, of its 

 food, was Leptodora hyaliiia, an Entomostracan unknown to Dr Baird, 

 and which, for its extraordinary tenuity, delicacy, and transparency, and 

 its totally different form from that usual among Cladocera, was no doubt 

 passed over by my old friend as something he could not make out, though 

 it is much larger than the species he satisfactorily determined. A * more 

 dainty dish to set before a ' fish cannot well be imagined than Leptodora 

 hyalina, an animal so transparent that, notwithstanding its size, it can 

 scarcely be detected in a glass of water unless held up against the light.

 Vidensk. Forhandl.), 1882, p. 45, pi. i. fig. 7. 



Rostrum well rounded at the extremity. Carapace with a single central 

 spine, and a second small tubercle-like spine on the central line behind it, 

 without the lobe-like folds of fasciatus, and the sulcus, which in that 

 species defines their lateral regions much less distinct and deep. Antennal 

 scale not greatly widened at the base. Last joints of maxilliped not broadly 

 flattened. Second pereiopod longer, reaching one-third the length of the 

 hand of first pair ; its chela very weak, the finger and thumb parallel and 

 touching each other, and apparently altogether too feeble to be used for 

 grasping. Body not speckled with brown. Carapace more or less suffused 

 with rufous or chestnut colour ; a band across the fourth segment of pleon, 

 and a second across the telson and uropods of the same colour.
