CiRC. No. 66. 

 also forms the lower part of the cliff between Old Nab and Staithes. 

 The doggers in this zone, about midway, are very fossiliferous. At 

 Staithes there is a considerable fault; the beds on the north are 

 thrown up, so that the A. ma?-garitatus zone forms the summit 

 instead of the bottom only of the cliff, and the A. serpentmus, which 

 at Rosedale Wyke formed the scars, is soon 375 feet high in Rock- 

 cliff. From Staithes to Boulby the cliffs are capped with Boulder 

 Clay, which creeps up and covers a large portion of the surface 

 towards the central moors. From Saltburn to Redcar there is a fine 

 stretch of sand, with low boulder clay cliffs ; whilst at Redcar itself 

 may be seen at low water some Lias scars of the A. bucklandi zone. 



Botany. 



Messrs. T. F. Ward and M. B. Slater inform us that a list of 

 the rarer plants growing in the neighbourhood of Saltburn is given in 

 Baker's ' North Yorkshire,' and that Ferguson's ' Natural History of 

 Redcar' also contains a good list of the rarer plants of that district. 

 The present season is a late one — therefore only the early flowering 

 plants may be expected to be met with. The following comprises 

 some which have been recorded from the district in the works just 

 mentioned : — Cakile ?nariiima, Silene maritima, Euonymus europceus, 

 Asperula odorata, Myosoiis sylvatica, Anthyllis vulneraria, Vicia 

 syivatica, Prunus padus^ Linaria cymbalaria, Plantago coronopus^ 

 P. inarititna^ and Crambe niaritima. The following are some of the 

 rarer mosses recorded from the district : — Fissidens crassipes, 

 Dicranu7n fuscescens, Distichium capillacemn, Gyinnostomu7n 7'iipestre, 

 Dicranella rufescens, Didymodon flexifolius, Grimmia niaritima, 

 Orthotrichuju tenellum, Aidacomnium androgynum^ Tetradontium 

 broivnianum, Trichostomum tophaceum, and Hyocomiiuii flagellai-e. 

 The stream which flows into the sea at Saltburn has its source near 

 Roseberry Topping, and in its lower course flows through a fine 

 wooded glen, which will probably be one of the best localities for 

 plants at this early season, and it is possible some good finds in 

 Hepaticse would reward diligent search. Damp places on the coast 

 cliffs are also often good localities for mosses. 



Lepidoptera. 



Mr. G. T. Porritt, F.L.S., whose observations on the Lepidoptera 

 of Saltburn may be referred to at pp. 67 — 69 of the ' Naturahst ' for 

 March, remarks that so far as perfect insects are concerned, the date 

 of the meeting is too early. Nearly all the species alluded to in that 

 paper will be in the larval state, and members who want them can 

 collect them in that stage. Those of the interesting and local 

 Pierophorus dichrodadylus ought readily to be found in stems of tansy, 

 which grows in abundance in a ravine not far from the Saltburn 

 Pleasure Gardens, and those of Agrotis valligera and A. tritici will 

 be feeding, the latter in profusion, beneath the sand along the sand- 

 hills between Saltburn and Redcar. The Depressarise seem well 

 represented in the district, and it will be just the right time for well- 

 grown larvae of most of the species on their various food-plants. Of 

 the two species for which we have as yet no other Yorkshire locality, 

 D. douglasella and D. weirella, the former is said to feed on wild
