]\Ir. Slater's v.-arehoiise to view a giant Ammonite. This colossal 

 specimen is 4 feet in diameter, and the breadth of the outer whorl 

 close to the mouth is 21 inches. So far as at present known, the 

 species of Anmionite is extremely rare, the British Museum only 

 ha^-ing a portion of one. This specnnen is the largest cretaceous 

 Ammonite known, and is named A. Jeptophyllus. It was found in a 

 pit in the flint chalk on Thixendale Wold. It has been carefully 

 mounted in cement by Mr. S. Chadwick, and set in a frame. We 

 were informed the weight of this specimen is about 3 cwt. The 

 members and Malton friends then had tea, at the conclusion of 

 which Professor Green, F.R.S., expressed his appreciation of the 

 kindness of Messrs. Chadwick and Slater in conducting so success- 

 fully such a rich and practical field excursion. He emphasised 

 strongly the value of the Tvlalton Museum, stating it was one of the 

 best he had seen ; it was of the greatest possible value to the 

 inhabitants, and reflected the utmost credit upon the hard-working 

 and painstaking curators. Messrs. C. Bro^^'n^idge, F.G.S., and 

 the writer, also expressed similar opinions. The privilege was 

 then granted of viewing Mr. Chadwick's private collection at his 

 residence at Norton. He exhibited a number of groups of beautifully 

 shaped sponge spicules from the chalk. These minute fossils under 

 the lens revealed a great variety of wonderful forms. As Mr. Chadwick 

 has made the study of fossil sponges his special Hne of research, he 

 was good enough to review the various forms, classifying and ex- 

 plaining them. His collection of Cretaceous and Oohtic fossils 

 comprise literally thousands of fine and typical specimens, and it 

 would require a special excursion even to hurriedly glance over 

 them. 



XO TE—EXTOMOL OGY. 

 YorksMre Neuroptera and Orthoptera.— I am anxious during the 



present and several future seasons to work up the Xeuroptera and Orthoptera of 

 our county as much as possible, ^dth a view to publishing a list of species, va\\v 

 their localities, etc., and shall be ven,- grateful to all entomologists (or other 

 naturalists) who, when out collecting their own particular groups of objects, will 

 kindly kill and pin (of course they need not trouble to set them) one or two or 

 three specimens of any species they may come across, and send them to me at the 

 end of the season — or oftener if it be not too much trouble. The families in the 

 Xeuri rtera wanted are xh& Libelhflidtr (Dragon-flies), Pcrlida: ( Stone-flies i, Sialzdce, 

 - -r. Sl€ (Snake-flies), Osriiylidi?. Hernerohidi^, Chrysopidu (Lacewing-flies), 

 C:K:::-rygida:, Pajiorpidcc (Scorpion-flies), and the Trichopiera (Caddis-flies). 

 T..r : , other British groups, Psocidi.z and Ephemej-idcr (May- flies), I do not 

 y . • -r to touch at preser.t. The Orthoptera include the Fo7-fic7iUdcz. (Ear\rigs),
