Dear Sir

In answer to your letter (of April 7^th.) containing a drawing of the valves of a Verruca, I ventured to ask you to be so good as to inform me by what name you intended calling it. I sh^d. also be glad to know whether the outline of the plate, to which the adductor muscle is attached in the fixed scutum, has the almost angular outline as represented by you, or whether it has been broken:¹ I sh^d. be very glad to know, also, whether the basal point of the free or movable tergum is as much rounded, naturally & without attrition, as represented by you.²

I presume your volume will now be soon published.³

I beg to remain, with much respect, & hoping for an answer,— | Dear Sir | Your’s faithfully | Charles Darwin
