BOSTON THEATRE. 7.45 P.M. Matinee, Saturday, at 2. The "Princess Toto" will be continued until further notice. It is a bright comic opera, written by Mr. Frederic Clay; the libretto, by Mr. Gilbert, is clever, as we expect everything from his pen to be. The romantic Princess Toto is afflicted with a complete want of memory; this leads to many curious complications, when she successively runs away with a party of bandits and a band of Indians, and is pursued by Prince Doro and by Caramel, both aspirants to her hand. Miss Braham's acting as the Princess is good; her singing not always so. Mr. Cambell's Doro and Mr. Montgomery's King Portico are very good. Some of the choruses are very effectively rendered.

BOSTON MUSEUM. 7.45 P.M. Matinees, Wednesday and Saturday, at 2. To-night, and Sat. Matinee, Boucicault's "Old Heads and Young Hearts," with Mr. Warren as Jesse Rural. Saturday evening, Miss Martinot's benefit, - the "Spark," "Asmodeus," and the "Little Rebel." March 29, "Robinsonnade," and "The Lark," which promise to be very amusing.

GAIETY THEATRE. 8 P.M. Matinees, Wednesday and Saturday, at 2. To-night and to-morrow, Tony Denier's Pantomime Troupe give "Humpty Dumpty" in a very amusing way. Next week, "The Very Merry Mariner," a comic opera, which was first brought out in German in New York as "Der Seecadet." In English, under the title "The Royal Middy," it has proved very successful.

GLOBE THEATRE. - 7.45 P.M. Matinees, Wednesday and Saturday at 2. "The Pirates of Penzance" has already been seen by so many that it is hardly necessary to speak of its merits. Mr. Gilbert's libretto is wonderfully amusing. The music, though fortunately not so catching as that of "Pinafore," is charming. The singing and acting by D'Oyley Carte's Company are much above the average; the choruses, strikingly good.

PARK THEATRE. - 7.45 P.M. Matinee, Saturday, at 2. Mr. Booth continues to draw large houses, notwithstanding the attractions of the comic operas. To-night, he gives his wonderful impersonation of the Fool, in the "Fool's Revenge," for the last time. Sat. Matinee, "Don Caesar de Bazan"; Sat. evening, "Richard III." March 22 (last week), "Macbeth"; 23d, "Hamlet"; 24th, "Richard III.": 25th, "Richelieu"; 26th, "Much Ado about Nothing"; 27th, Matinee, "Ruy Blas"; 27th, "Merchant of Venice" and "Taming of the Shrew." On the 29th, the Florences will be here in the "Mighty Dollar."
