circularis, Nymphon pellucidum, and N. minutum but j 

 several of his species, among them these two Nymphons, 

 are, to quote Stebbing, " foundlings which still utter feeble 

 but unanswered cries for recognition." 



Leslie and Herdman, in their catalogue of Forth Marine 

 Invertebrata, 1881, gave only two species, Pycnogonum 

 littorale, Miill., and Nymphon gracile, Leach, but it is ques- 

 tionable if the latter name was correctly applied. In 1884 

 Dr Henderson {I.e.) reported three additions, namely, Nymphon 

 hirtiim, Kroy., N. hrevirostre, Hodge, and N. grossipes, 0. Fab., 

 and considered he had other two species unidentified. In 

 a catalogue of the Crustacea and Pycnogonida in the 

 Museum of University College, Dundee, dated 1901, which 

 Professor D'Arcy Thompson has kindly sent me, the fol- 

 lowing are entered from the Firth of Forth : — Nymphon 

 rubrum, Hodge, Chcetonymphon hirtum (Fabr.), Pallene hrevi- 

 rostris (Johnst.), and Anoplodactyhcs petiolatus (Kr.).2 In 

 1902, Pearcey (I.e.) recorded Nymphon gallicum, Hoek, which 

 is the same as N. gracile, Leach. When shore-collecting 

 I have occasionally found a few Pycnogonids, but have 

 seldom troubled to preserve them. Those I have kept were 

 got under stones between tide-marks, at North Berwick, in 

 January 1896, and belong to two species, the common 

 Pycnogonum littorale, Strom, (several, one with large cluster 

 of ova attached), and Phoxichilidium femoratum (Eathke), 

 $ and $ The last-named does not appear to have been 

 previously recorded from the Firth, and brings the number 

 of species known from its waters up to ten. 



The number of British Pycnogonida is uncertain. Accord- 

 ing to Stebbing, " we can with some assurance boast of ten 

 genera, and twice that number of species," but a higher figure 

 has been named. Surely the Firth of Forth ought to be 

 able to produce at least a dozen " no-bodies " if properly 

 pressed to yield up its treasures.

2 Professor D'Arcy Thompson tells me they now have also N'. hrevirostre, 

 Hodge, and Pycn. littorale, Strom., from the Firth.
