eggs. When the jar is full tie it over with thick 

 brown paper. The eggs, I venture to assert, will not 

 explode when boiled, indeed " Master's eggs " were 

 favourites with our cook ; } when eaten at three 

 months old you could not tell them from new laid 

 eggs. — H M. Hardwickc. 



Corrigenda.— Will readers of the note on "The 

 Parietal Eye of Lizards " cross out the lapsus calami 

 of " pituitary body,"and insert pineal body in its stead. 

 Also of my other note, in the same number, called 

 " The_Development of the Tadpole" will they read 

 epididym/'j for epididymus.— J. IV. Williams. 



Arion Bourguignati.— On February 27th, in 

 company with Mr. F. G. Fenn, I found A. botlrgui- 

 gnati abundant at Isleworth, living with A. hortensis, 

 from which it may readily be distinguished by its 

 keel in the young state, and in the adult by the 

 narrower and differently-placed bands,' curious pep- 

 pery-gray appearance, and perfectly white foot-sole. 

 This species, which we have also found at Bedford 

 Park, is new to the fauna of Middlesex. While 

 writing, I may mention that the white variety of 

 Helix Cantiana, described by Taylor in 1SS3 as var. 

 albida, was originally named var. alba by Colbeau in 

 1866, which latter name must of course be used. —

Cambridge Entomological Society.— At the 

 anniversary meeting ,of the Society, Mr. Brown 

 exhibited a specimen of C. Celerio captured in Cam- 

 bridge. The exhibits also included A. prunaria, 

 N. heurica, and other moths chiefly captured in 

 Monk's Wood. After the election of officers, the 

 programme for the year was drawn up, and includes 

 excursions to Chippenham, Wicken, Monk's Wood, 

 and other good localities. It was decided that 

 students in other branches of Natural History and 

 other non-members will be welcome at the excur- 

 sions, and Mr. Alfred Jones (Librarian), 59 Trumping- 

 ton Street, has kindly offered to receive the names 

 of those wishing to do so, and to supply information 

 to them, which may also be obtained of the Secre- 

 tary, Mr. C. B. Holman Hunt (St. John's). 



Shells at Lucerne. I spent a couple of hours 

 in the " Gletscher-Garten," when passing through 

 Lucerne last September, and collected the following 

 Mollusca : Pisidiitm — (a single specimen) ; Succinea 

 clegans, Risso (ditto) ; Helix arbustorum, L. (all 

 of a very dark colour) ; // pomatia, L. (common) ; 

 H. rotnndata, Mull, (not very plentiful) ; H incarna- 

 ta, Mull, (common and beautifully coloured) ; H. his- 

 pida, L. (very few specimens occurred) ; H. ne- 

 moralis, L. (libellula 1 2345, and rubella 00000); 

 //. lapicida, L., H. obvoluta, Mull, (occasional speci- 

 mens) ; Hyalina nitidula, Drap. (in extreme plenty) ; 

 H. Draparnaldi, Beck, (rare) ; Clausilia laminata, 

 Mont, (scarce) ; C.plicaia, Drap., C. cntciata, Stud., 



C. parvula, Stud, (very plentiful on the face of the 

 rock, in all stages of growth : many specimens decol- 

 late) ; Cochlicopa luhrica, Mull, (common just by the 

 " Lion."). Outside the town, I found Pomatias scplem- 

 spirale, Raz., Pupa frumentum, Drap., Helix villosa, 

 Stud., Bulimus montanus, Drap. — Brockton Tomlin,

The Reproduction of the Lost Tails of 

 Lizards. — In page 38 cf the current year of Science- 

 Goss t p, F. G. S. appears to doubt whether full-grown 

 lizards can reproduce lost tails. — Last year, in the 

 month of June, I caught a large specimen of Lacerta. 

 vivipara with but a stump tail, clearly full-grown. 

 Before the end of the summer, a new tail one inch 

 and a half long was produced. I have a young one of 

 the same species which has repaired its tail, and a 

 large specimen of Lacerta viridis which has twice 

 lost its tail, that reproduced having been partially 

 again lost and reproduced, the two cicatrices very 

 plainly show the extent of each reproduction. I 

 have also a Lacerta agilis which has lost its tail and 

 reproduced it before it came into my possession ; 

 there is, or was recently living, in the gardens of the 

 Zoological Society, a Lacerta agilis, which has had 

 its tail broken, and at the fracture has produced a 

 second tail without losing the original, so that it now 

 presents the singular appearance of a lizard with 

 two tails. I have noticed that the females are more 

 subject to the loss of tails than the males ; they are 

 not quite so agile, and their tails are nipped off by 

 birds after the bodies have entered a hiding-place. —

ANIMAL PSYCHOLOGY. 



Cats. — Cats are not commonly credited with so 

 much intelligence as dogs ; but I once knew a cat 

 whose mental powers would compare favourably 

 with those of the dogs mentioned in your last 

 number. This animal belonged to a woman who 

 kept a little school in a back room upstairs on the 

 same floor with another room, occupied by a working 

 man and his wife, who also kept a cat. It may be 

 readily believed that the neighbourhood was more 

 remarkable for the density of its population than for 

 their education, or piety, as was then the case with 

 many parts of London before the School Board had 

 yet asserted its supremacy. Cats' meat was sold on 

 Sunday as on other days of the week. The woman 

 who kept the school however, did not buy it on that 

 day, but procured enough on Saturday to last her 

 cat till Monday. Her neighbour did not imitate her 

 in this, but bought a halfpennyworth of cat's meat 

 on Sunday as on any other day. The conduct of the 

 cats became as different as that of their respective
