safe anchorage ; and although strongly represented as to genera 

 in this zone, we incline to believe that many were derived from 

 neighbouring spots, and were drifts, on account of the frequently 

 battered and misshapen condition of the specimens, as though 

 they had been driven at the mercy of the waves. A few of the 

 stronger forms remain uninjured, and of these I have collected 

 perfect series from the young state upwards. Such would be as 

 genera of the division Glistenterata the following: — Waldheimia 

 perforata, Waldheimia indentata, Waldheimia resupinata, Tere- 

 hratula glohulina, and Waldheimia Marice, also Bhynchonella 

 amalthei ; the two latter new to English science. My accom- 

 plished friend, Mr. Davidson, F.R.S., &c., having requested me to 

 prepare a catalogue of the whole of the Brachiopoda collected by 

 me at Churchdown, which he and the MM, Deslongchamps and 

 EoMER unite in declaring an important position palseontologically, 

 I have, accordingly, tabulated them so as to show the true range 

 of the species through the Lias vertically, and will refer to this 

 table which is printed in the Palseontograph, Soc, 1877, in Mr. 

 Davidson's Supplement, Part II, merely here giving the bare 

 results shortly expressed. The whole number of species of 

 Brachiopoda collected by me from our Lias would be of the 

 Tretenterata division, two genera only ; and of the Glistenterata 

 32 genera, making a total of 34 genera of Brachiopoda. The 

 whole with the exception of one or two from the Communis Zone, 

 were sent to Mr. Davidson, and verified by him. Now of these 

 genera, all belonging to the Glistenterata division, 19 are found 

 in our Spinatus beds at Churchdown. The absence of genera of 

 the other great division Tretenterata, I have sought to account for. 

 Besides these numerical results, it is important to note the range 

 vertically of each species : hitherto I have succeeded in extending 

 the range of some of them : T. glohulina, and W. resupinata, 

 formerly marked in the Am. Margaritatus Zone, I have detected 

 in the Spinatus Zone, and so forth. The foreign species were 

 sent by me to M. J. Etjdes Deslongchamps, at Caen, who at 

 once recognized them, and hailed the little Bhynchonella amalthei 

 QuENSTEDT, as an old acquaintance of his. The more minute 

 Brachiopoda found by Mr. Moore in that portion of the Middle
